Answer:
The number of total students in the class is 55
Step-by-step explanation:
We will use the ratio method to solve the question
∵ The number of boys and girls in a class are in the ratio 4: 7
∵ There are 15 more girls than boys
→ That means the difference between them is 15
∵ The difference between the terms of their ratio = 7 - 4 = 3
→ By using the ratio method
→ boy : girl : difference
→ 4 : 7 : 3
→ x : y : 15
→ By using cross multiplication
∵ x × 3 = 4 × 15
∴ 3x = 60
→ Divide both sides by 3
∴ x = 20
∵ y × 3 = 7 × 15
∴ 3y = 105
→ Divide both sides by 3
∴ y = 35
∵ x represents the number of boys
∴ The number of boys is 20
∵ y represents the number of girls
∴ The number of girls is 35
∴ The total number of students = 20 + 35 = 55
∴ The number of total students in the class is 55

"I am 3 times as old as Sue is," Frank said to Ann. "On the other hand, I am 15 years older than John while Sue is 1 year younger than John. How old am I?"
If J represents John's age, then which of the following equations could be used to solve the problem?
J + 15 = 3J - 1
3(J + 15) = J - 1
J + 15 = 3(J - 1)
J + 15 = 3(J - 1)

Gabe bought five sacks of apples each sack weighed 12 lb he paid three for each pound of apples what was the total cost of all of the apples Gabe bought
Answer:
The cost of 12lbs of apples is $36.
Step-by-step explanation:
⟹ Lets Solve!
⟹ First we must define x and y.
x is the lb's of apples and y is the cost.
⟹ Now lets form our equation.
[tex]3x = y[/tex]
[tex]x = 12[/tex]
⟹ Since gabe bought 12 pounds of apples x = 12.
⟹ Now substitute x for 12.
[tex]3x = y[/tex]
[tex]3(12)= y[/tex]
⟹ Now multiply.
[tex]36 = y[/tex]
The cost of 12lbs of apples is $36.

What is the solution for x in the equation?
9x - 20 - 4x = 40?
X=1/4
X=4
X=12
X=1/12
Answer:
x = 12
Step-by-step explanation:
9x - 20 - 4x = 40
Combine like terms
5x -20 = 40
Add 20 to each side
5x -20+20 = 40+20
5x = 60
Divide by 5
5x/5 = 60/5
x = 12
9x - 20 - 4x = 40
By transposition method, we get
9x - 4x = 40 + 20
By simplifying the like terms, we get
5x = 60
or, x = 60/5 = 12
The value of x is 12.
4. Mariana receives a $20 gift card for
downloading music and wants to
determine how many songs she can
purchase. Each downloaded song costs
$1.29
a.
Let m represents the number of songs
downloaded. Write an inequality that
represents this given situation?
b. What is the maximum number of songs
Mariana can download?
Answer:
inequality- 1.29m <20
maximum number of songs- 15 songs
Step-by-step explanation:
For the inequality, you see that she only has $20 so whatever she buys has to be below that so use the less than sign. You also see that each song is worth $1.29 so 1.29m. For the maximum number of songs, you divide 20 by 1.29 and just ignore the remainder.

Answer:
A
Step-by-step explanation:
1. Honestly, my course of action, if allowed to, would be to use my graphing calculator. Obviously, you can graph the first equation but the second one requires some rearranging, keeping in mind that we are isolating the y.
[tex]2y-2x=10[/tex]
[tex]2y=2x+10[/tex]
[tex]y=x+5[/tex]
So now we have an equation of the line. Simply enter both of these equations into your graphing calculator and you're all set.

What is the reflected image in the x-axis A(- 1, 8), B(- 8, 8) C(- 5, 1) ?
Answer:
[tex]A' = (- 1, -8)[/tex]
[tex]B' = (-8, -8)[/tex]
[tex]C' = (-5, -1)[/tex]
Step-by-step explanation:
Given
[tex]A = (- 1, 8)[/tex]
[tex]B = (-8, 8)[/tex]
[tex]C = (-5, 1)[/tex]
Required
Determine the reflected image in the x axis
When a point is reflected across the x axis, the x coordinate remains the same, while the y coordinate is negated.
In other words,
[tex]A(x,y)[/tex] when reflected becomes [tex]A'(x,-y)[/tex]
So, for each of the following points
[tex]A = (- 1, 8)[/tex]
[tex]B = (-8, 8)[/tex]
[tex]C = (-5, 1)[/tex]
There images are:
[tex]A' = (- 1, -8)[/tex]
[tex]B' = (-8, -8)[/tex]
[tex]C' = (-5, -1)[/tex]
Find the volume of the solid. *
7)
Answer:
B
Step-by-step explanation:
The volume (V) is calculated as
V = area of triangular face × depth
Area of triangle = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here b = 3 and h = 4 , then
A = [tex]\frac{1}{2}[/tex] × 3 × 4 = 6 Km²
Now depth = 2, thus
V = 6 × 2 = 12 Km³ → B

Answer:
Company B offers the lowest price per pound of 12.72
Step-by-step explanation:
Unit Price
Given a product that costs X dollars and has Y pounds, the unit price is given by X/Y dollars per pound.
Elle is comparing prices to purchase candy online. Company A offers 2 1/2 pounds of chocolate for $32.50 and Company B offers 2 3/4 pounds of chocolate for $35.00.
The offer of Company A is for 2 1/2 pounds = 2.5 pounds
The offer of Company B is for 2 3/4 pounds = 2.75 pounds
The unit price for Company A is $32,50/2.5 = $13/pound
The unit price for Company B is $35,00/2.75 = $12.72/pound
Company B offers the lowest price per pound of 12.72
