Amy compared 4/2 and 5/8 by first comparing each fraction into 1
Amy compared the fractions 4/2 and 5/8 by converting each fraction into a whole number.
To compare fractions, Amy converted each fraction into an equivalent form with a common denominator of 1. For 4/2, she multiplied both the numerator and denominator by 2 to get 8/4. Then, she simplified it to 2/1, since both the numerator and denominator are divisible by 4. Similarly, for 5/8, she multiplied both the numerator and denominator by 8 to get 40/64. Amy then simplified it to 5/8 by dividing both the numerator and denominator by their greatest common divisor, which is 8.
Comparing the two fractions, Amy found that 2/1 is greater than 5/8. This means that 4/2 is greater than 5/8 when comparing the fractions as whole numbers. It is important to note that comparing fractions by converting them to whole numbers may not always provide an accurate comparison. Other methods, such as finding a common denominator and comparing the fractions directly, are more reliable.

khalil has sold 20 candy bars and then sold 6 bars every 8 hours. Write the equation
The equation representing the number of candy bars Khalil has sold can be written as n(t) = 20 + 6(t/8), where n(t) is the number of candy bars sold and t represents the number of hours since the initial sale of 20 bars.
Initially, Khalil sold 20 candy bars. After that, he sold an additional 6 bars every 8 hours. To represent this situation with an equation, we can use the function n(t), where n is the number of candy bars sold and t is the number of hours since the initial sale.
Since Khalil sold 20 candy bars initially, we start with that as the base value. Then, for every 8 hours that pass, he sells an additional 6 bars. We can represent this using the equation n(t) = 20 + 6(t/8), where t/8 represents the number of 8-hour intervals that have passed since the initial sale.
By substituting different values of t into the equation, we can calculate the number of candy bars Khalil has sold at different points in time. For example, if t = 8, it means 8 hours have passed since the initial sale, and Khalil would have sold 20 + 6(8/8) = 26 candy bars.

I need to make a math problem out of these segments:A |——|——|——|. (The last two segments of A is 18) |B |——|Please help, fast!
Here's a math problem using the given segments:
A and B are two line segments on a number line. Segment A is divided into three equal parts, and the length of the last two parts combined is 18 units. Segment B is not divided and has an unknown length. What is the length of segment B?
In the given problem, segment A is divided into three equal parts represented by the three "|" symbols. We are told that the length of the last two parts combined is 18 units. Let's assume the length of each part of segment A is x units.
Since the last two parts combined equal 18 units, we can set up the equation: 2x = 18. This equation represents the fact that the sum of the lengths of the second and third parts of segment A is 18 units.
To find the value of x, we divide both sides of the equation by 2: 2x/2 = 18/2. This simplifies to x = 9. Therefore, each part of segment A has a length of 9 units.
Now, segment B is represented by "|B ". It is not divided, so its length is simply x units, which is 9 units. Therefore, the length of segment B is 9 units.

averi bought a 6 ounce can of pecans for 4.89 . what was the unit price
The unit price of the pecans is $0.815 per ounce (rounded to three decimal places).
To calculate the unit price, we divide the total cost of the item by the quantity purchased. In this case, Averi bought a 6-ounce can of pecans for $4.89.
To find the unit price, we divide the total cost ($4.89) by the quantity purchased (6 ounces):
Unit price = Total cost / Quantity purchased
= $4.89 / 6 ounces
To simplify the unit price, we can divide both the numerator and denominator by their greatest common divisor (GCD). In this case, the GCD of 4.89 and 6 is 3.
Dividing both the numerator and denominator by 3, we get: Unit price = ($4.89 / 3) / (6 ounces / 3)
= $1.63 / 2 ounces
Therefore, the unit price of the pecans is $0.815 per ounce (rounded to three decimal places). This means that Averi paid approximately $0.815 for each ounce of pecans she purchased.

The required Olivia has read approximately 75.26% of the pages, and Olivia has not read approximately 24.74% of the pages.
Part A:
To represent the proportion for the percent of pages that Olivia has read, we can use the equation:
(Number of pages read) / (Total number of pages) = (Percent of pages read) / 100
Given:
Book 1: 40 pages out of 40 pages
Book 2: 60 pages out of 85 pages
Book 3: 43 pages out of 65 pages
Total number of pages read = 40 + 60 + 43 = 143 pages
Total number of pages = 40 + 85 + 65 = 190 pages
Plugging in these values into the proportion, we get:
143 / 190 = (Percent of pages read) / 100
To find the percent of pages read, we can solve for (Percent of pages read):
(Percent of pages read) = (143 / 190) * 100
(Percent of pages read) ≈ 75.26%
Therefore, Olivia has read approximately 75.26% of the pages.
Part B:
To find the percentage of pages that Olivia has not read, we can subtract the percentage of pages read from 100%.
Percentage of pages not read = 100% - (Percent of pages read)
Percentage of pages not read = 100% - 75.26%
Percentage of pages not read ≈ 24.74%

is the value of z, the side length of the bottom square?
We find: z = x Therefore, the value of z, the side length of the bottom square, is equal to the side length of the top square.
Let's assume the side length of the top square is x. Since the right triangle is formed by joining the squares at their vertices, the hypotenuse of the triangle is the diagonal of the top square.
In a square, the length of the diagonal is equal to the side length multiplied by the square root of 2. Therefore, the hypotenuse of the right triangle is x * √2.
The two legs of the right triangle are the side lengths of the squares adjacent to the hypotenuse. In this case, one leg is z, the side length of the bottom square.
Using the Pythagorean theorem, we have the equation:
z^2 + z^2 = (x * √2)^2
Simplifying the equation, we get:
2z^2 = 2x^2
Dividing both sides by 2, we have:
z^2 = x^2

If (x – 3)2 = 5, what values of x make the quadratic equation TRUE?.
The quadratic equation (x - 3)^2 = 5 can be rearranged into the standard form x^2 - 6x + 4 = 0. We need to find the values of x that satisfy this equation.
To find the values of x that make the quadratic equation (x - 3)^2 = 5 true, we can rearrange it into the standard form:
(x - 3)^2 - 5 = 0.
Expanding the square, we get:
x^2 - 6x + 9 - 5 = 0,
x^2 - 6x + 4 = 0.
Now, we have a quadratic equation in the form ax^2 + bx + c = 0, with a = 1, b = -6, and c = 4. To solve this equation, we can use factoring, completing the square, or the quadratic formula.
In this case, we can try factoring:
(x - 2)(x - 2) = 0,
(x - 2)^2 = 0.
Taking the square root of both sides:
x - 2 = 0,
x = 2.
So, the only value of x that satisfies the equation is x = 2.
Therefore, the solution to the quadratic equation (x - 3)^2 = 5 is x = 2.

On the first day of the year, Candace has $700 in her bank account. She spends $35 per week. Spencer starts the year with $450 in their bank account. They save $15 per week.
Which equation can be used to solve for the number of weeks, w, it will take for Candace and Spencer to have the same amount of money in their accounts?
The number of weeks required to have same amount in the Candace and Spencer account is equal to 5 weeks.
Amount in the bank account = $700
Amount spent per week = $35
To find the number of weeks it will take for Candace and Spencer to have the same amount of money in their accounts,
Set up the following equation,
$700 - $35w = $450 + $15w
$35w represents the amount Candace spends after w weeks,
and $15w represents the amount Spencer saves after w weeks.
By equating the amounts in their accounts,
solve for the number of weeks, w, it will take for them to have the same amount of money.
To solve the equation,
$700 - $35w = $450 + $15w
Simplifying the equation,
$700 - $450 = $15w + $35w
⇒$250 = $50w
Next, divide both sides of the equation by $50 to isolate the variable w,
⇒$250 / $50 = w
⇒5 = w
Therefore, it will take 5 weeks for Candace and Spencer to have the same amount of money in their accounts.

Two cyclists meet at the library and then go for a bike ride.
The distance each person has traveled from her home at x
hours from the start of the ride is linear, as shown.
Which statement must be true?
Two cyclists meet at the library and then go for a bike ride. The distance each person has traveled from her home at x hours from the start of the ride is linear, as shown.
Let's assume that cyclist A and B start at a distance x and y, respectively, from the library. Further, let's assume that cyclist A starts at t = 0. Then, the distance from the library for cyclist A at t hours after the start of the ride is represented by x + rt. The distance from the library for cyclist B at t hours after the start of the ride is represented by y + st.As the question says, the distance each person has traveled from her home at x hours from the start of the ride is linear. Thus, we can write their distances from the library as:dA(x) = x + rtdB(x) = y + st, where dA and dB represent the distance covered by cyclists A and B respectively.Now, if we want to find out the distance between the two cyclists at x hours after the start of the ride, we can use the following formula:distance between the two cyclists = dB(x) - dA(x)= (y + st) - (x + rt) = (y - x) + (s - r)tSince s and r are constants, the expression (y - x) + (s - r)t is linear with respect to t. Hence, the statement "The distance between the two cyclists is a linear function of x" must be true.

How long will it take me to travel a distance of 12 km at the average rate of 5m/s
To find out how long it will take to travel a distance of 12 km at an average rate of 5 m/s, we can use the formula for speed:
Speed = Distance / Time
Rearranging the formula to solve for time, we have:
Time = Distance / Speed
Substituting the values, we have:
Time = 12 km / 5 m/s
To perform the calculation, we need to convert the distance to meters since the speed is given in meters per second. There are 1000 meters in 1 kilometer, so 12 km is equal to 12,000 meters.
Now, we can substitute the values into the formula:
Time = 12,000 meters / 5 m/s
Dividing 12,000 by 5, we get:
Time = 2400 seconds
Therefore, it will take approximately 2400 seconds to travel a distance of 12 km at an average rate of 5 m/s.

Select all the points that are on the line with a slope of 2 that also contains the point (2,-1)
The equation of the line that passes through the point (2, -1) and has a slope of 2 is y -(-1) = 2(x-2) or y = 2x-5. This line passes through an infinite number of points, so we need to identify all the points that are on the line.
To do this, we can substitute different values of x into the equation and find the corresponding y-values. Then, we can pair each x-value with its corresponding y-value to get a point on the line. Here are a few points that are on the line with a slope of 2 that also contains the point (2,-1): (0, -5)(1, -3)(2, -1)(3, 1)(4, 3)(5, 5)Note that we could have chosen any value of x and found the corresponding y-value using y = 2x - 5. Therefore, there are more than 100 points on the line with a slope of 2 that also contains the point (2, -1).
