Step-by-step explanation:
"five more than the product of four and a number is
equal to the product of three and that same number
increased by six."
A. X=-1
B. X= 1
C. X= 3
D. X= 1/2
Answer:
B
Step-by-step explanation:
Let the number = x
Product: 4 * x
Add 5: 4x + 5
=
3x + 6
Now equate the two parts.
4x + 5 = 3x + 6 Subtract 5 from both sides
4x + 5 - 5 = 3x + 6 - 5 Combine
4x = 3x + 1 Subtract 3x from both sides
4x-3x=3x -3x + 1 Combine
x = 1
Seven times the sum of a number and 1 is 28.
What is the number?
Enter your answer in the box.
The number is
The number in the question that gives 28 after the operations is; 3
We are told that the product of seven and the sum of a number and 1 is 28.
Let the number be x. Thus;
7(x + 1) = 28
Use division property of equality to divide both sides by 7.
7(x + 1)/7 = 28/7
(x + 1) = 4
Use subtraction property of equality to subtract 1 from both sides to get;
x + 1 - 1 = 4 - 1
x = 3
Therefore, in conclusion the number is 3.

Rita is making greeting cards, which she will sell by the box at an arts fair. She paid $24 for a booth at the fair, and the materials for each box of cards cost $3. She will sell the cards for $11 per box of cards. At some point, she will sell enough cards so that her sales cover her expenditures. How much will the sales and expenditures be? How many cards will that take?
Step-by-step explanation:
we need to find the number n of sold boxes, so that the income (sales) and costs (expenditures) are equal. this is called the break even point. any more boxes sold will then result in a profit, actually gaining money. and if she cannot reach that number of sold boxes, then she will make a loss.
so,
n×11 = n×3 + 24
n×8 = 24
n = 3
it will take 3 sold boxes of cards to break even.
at that point she will have spent $24 + 3×$3 = $33, and her sales will be 3×$11 = $33.

a group of 3 people are sharing chocolates each person wants 8 chocolates and each box has 6 chocolates
4 boxes of chocolates are needed by the group.
If a group of 3 people are together, needing 8 chocolates each. This means that the total number of chocolates needed is 8 × 3 = 24.
Again, we are told that each box contains 6 chocolates. This means that to get the number of boxes needed, we have to divide the total number of chocolates needed by the number of chocolates per box.
Essentially, 24/6 = 4 boxes of chocolates

What is 6 1/2 + 9 3/8
Answer: 15 7/8
Step-by-step explanation:
Add the whole numbers first 6+9 to getting 15
Now find the lowest common denominator for both the fractions. In this case it is 8.
3/8 would stay the same however 1/2 would become 4/8. 4/8 + 3/8 is 7/8.
15 add 7/8 is 15 7/8

£6000 is to be shared among David, Daniel and Dennis, Daniel is to get one and a half times as much as David, while Denis is to get three and a half times as much as David. Determine (i) the ratio in which the money is to be shared. (ii) the amount of money each will get.?
Answer:
(i) David: Daniel: Dennis= 2: 3: 7
(ii) David, Daniel and Dennis will get £1000, £1500 and £3500 respectively.
Step-by-step explanation:
(i) Let the amount of money obtained by David, Daniel and Dennis be x, y and z pounds respectively.
x +y +z= 6000 -----(1)
y= 1.5x -----(2)
z= 3.5x -----(3)
Let's write the amount of money each gets in terms of x.
David --- x
Daniel --- 1.5x
Dennis --- 3.5x
In ratio, David: Daniel: Dennis
= 1: 1.5: 3.5
= 2: 3: 7
This is obtained by multiplying 2 throughout the ratio as ratio is its simplest form is in whole numbers and does not have decimals.
_______
(ii) Now that we know how the money is shared in terms of ratio, we can easily determine how much each of them receives.
Total amount of money= £6000
Total number of units
= 2u +3u +7u
= 12u
Thus, 12 units represents £6000.
12u ----- £6000
1u ----- £6000 ÷12= £500
Amount of money David will receive
= 2u
= 2(£500)
= £1000
Amount of money Daniel will receive
= 3u
= 3(£500)
= £1500
Amount of money Dennis will receive
= 7u
= 7(£500)
= £3500
Extra notes:
• Units are represented by the letter 'u' in the working. They can also be called parts and their value is in relation to the total amount. Thus if David gets 2 units of the total money, and the total amount is 12 units, he receives 2/12 or ⅙ of the total sum of money.

could someone explian to me how to do these two? i’m not sure if i’m doing it right plz help
Step-by-step explanation:
Before I discuss how to graph both equations, I believe that it is essential to understand the variables and constant related to linear equations.
The slope-intercept form is: y = mx + b, where:
m = slope (which tells you the steepness of the line).
b = y-intercept: this is the point on the graph where it crosses the y-axis. Its coordinates is always formatted as, (0, b). The b is the y-coordinate of the y-intercept that you use for the equation.
The standard form of linear equations is: Ax + By = C, where:
A, B, C are integers (whole numbers, and cannot be in fraction or decimal forms). A and B ≠ 0, and A must be a positive integer.
Now that I have defined what the slope-intercept and standard form of linear equations are, we can proceed with working on graphing both equations.
7. y = -6x - 4In this equation, the slope (m) = -6, and the y-intercept (b) = -4. As an ordered pair, the y-intercept is (0, -4). In order to graph this equation, start by plotting the y-intercept on the graph. Then, use the slope (rise over run) to plot other points on the graph (6 units down, 1 unit run). Your next point should occur at (1, -10).
You could simply connect these two points and draw a line, or plot another point on the graph using the slope technique mentioned in this post.
8. 3x - 4y = 12This equation is in standard form, Ax + By = C. It is easier to graph a linear equation when it is in its slope-intercept form, y = mx + b.
In order to transform this equation into its slope-intercept form, start by subtracting 3x from both sides of the equation:
3x - 4y = 12
3x - 3x - 4y = - 3x + 12
-4y = -3x + 12
Next, divide both sides by -4 to isolate y:
[tex]\frac{-4y}{-4} = \frac{-3x + 12}{-4}[/tex]
y = ¾x - 3 ⇒ This is the slope-intercept form where the slope, m = ¾, and the y-intercept is b = -3.
Similar to how we graphed the equation from question 7, start by plotting the y-intercept, (0, -3). Then, use the slope of the equation, m = ¾ (3 units rise, 4 units run) to plot the next point. The next point should occur at (0, 4).
Attached are the graphed equations.
