The ratio 1:2 and 2:7 are not equivalent to each other.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
To get the real measurements from the given ratio, we need to assume to have some factor possibly cancelled from both the numerator and the denominator. Thus, a = px, b = qx
We are given the ratio as; 1:2 and 2:7
To find two ratios that are equal to 1:7, first write 1:7 as the fraction 1/7. ...
Next, multiply both the numerator and denominator
1/7 x 2 = 2/14,
or 2:14,
Now multiply the numerator and denominator
1/7 x3 = 3/21,
or 3:21.
Therefore, the ratio are not equivalent to each other.

What is the slope of the line?
Answer:
The slope is : -2/2
Step-by-step explanation:
To find the slope, start on the y-axis. -2 passes through the line on the y-axis so start there. Go up 2 unites, which will bring you to the origin. Now you need to reach -2 on the x-axis. Go left two units, which gives you 2/2. It's rise over run. It's -2 because you went left two units not right. When you go left, or down it'll be negative.
2 = rise
/
-2 = run
(x₁,y₁) = (-2,0)
(x₂,y₂) = (0,-2)
m = (y₂ - y₁)/(x₂ - x₁)
m = (-2 - 0)/(0 - (-2))
m = -2/2
m = -1

Help! i don't understand :/
Answer:
Option C
Step-by-step explanation:
Given inequality is,
-3(2x - 4) ≤ 7(3 - x)
Solve the given inequality further,
-6x + 12 ≤ 21 - 7x
(-6x + 12) + 7x ≤ (21 - 7x) + 7x
x + 12 ≤ 21
(x + 12) - 12 ≤ 21 - 12
x ≤ 9 Or {x real | x ≤ 9}
Therefore, Option C will be the correct option.

-6.05 + (-3.611)
-6.05 - 3.611
-9.661
Answer:
-9.661
Step-by-step explanation:
First of you want to plug in a and b making the equation
-6.05 + (-3.611)
or
-6.05 - 3.611
*I hope your teacher will allow you to use a calculator because of the decimals
Then you will add -6.05 + (-3.611) together
to get a negative answer of...

Jing just got a new job. She started at a pay rate of $12.50 per hour and will get a $0.50 raise each year. Max started a job where is salary is found by the equation y=x+10, where x is the number of years. What is the initial value for Jing?
Answer:
initial value for Jing is $12.50.
Step-by-step explanation:
It is given that Jing started at a pay rate of $12.50 per hour and will get $0.50 per year. So, 0.50 is slope and y intercept is 12.50 for this equation.
The y intercept represents the initial value for the Jing.
So, initial value is $12.50.

Answer:
0
-20
-7
Step-by-step explanation:
0 x any number = 0
4(-5) = -20
126/(-18) = -7
Answer:
1. 0
2. -20
3. -7
Step-by-step explanation:
1. 0 times anything is equal to nothing times something.
So, the first one is 0.
2. For 4 x -5, you can just do 4 x 5 x -1, which equals 20 x -1, whixh equals -20.
3. Remember, a negative times a negative = a positive. So, the number must be negative. Just do 126 / 18 x -1, which equals -7.
Hope this helps!!

He ratio of number of cookies to cost of cookies is 15:915:915, colon, 9. Let's find an equivalent ratio that shows the cost for 111 cookie. Hint #22 / 4 A ratio where one of the terms is 111 is called a unit rate. We can divide the number of cookies by 151515 to get to 111 cookie. Hint #33 / 4 \$\blueD9\div15=\$0.60$9÷15=$0.60dollar sign, start color #11accd, 9, end color #11accd, divided by, 15, equals, dollar sign, 0, point, 60 Hint #44 / 4 The cost of 111 cookie is \$0.60$0.60dollar sign, 0, point, 60.
Answer:
$0.60
Step-by-step explanation:
Given that:
The ratio of number of cookies to the cost of cookies as:
Number of cookies : Cost of cookies = 15 : 9
It means, we get 15[tex]x[/tex] number of cookies when we pay $9[tex]x[/tex].
To find:
An equivalent ratio to represent the cost of 1 cookie.
Solution:
Here, we have to find nothing but the unit price or the price of 1 cookie.
This can simply be done by dividing the total cost of cookies with the total number of cookies.
Total cost of 15[tex]x[/tex] cookies is given as $9[tex]x[/tex]
Using unitary method:
Let us divide both the sides with 15[tex]x[/tex], we get:
Total cost of [tex]\frac{15x}{15x}[/tex] cookies is given as [tex]\frac{\$9x}{15x}[/tex]
Total cost of 1 cookie is given as $0.60

Step-by-step explanation:
The quotient of two fractions is [tex]2\frac{2}{3}[/tex].
What is the division?The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.
Given that, 2/3 divided by 1/4
To divide fractions, keep first fraction as it is change division sign to multiplication and inverse the second fraction.
Here, 2/3 ÷1/4
= 2/3 ×4/1
= 8/3
= [tex]2\frac{2}{3}[/tex]
Therefore, the quotient of two fractions is [tex]2\frac{2}{3}[/tex].
