Answer:
D. 860 square inches
Answer:
D: 860 square inches
Step 1.
Remember:
w = 8
x = 5
y = 20
z = 11.3
Let's start with the bottom rectangular prism. The front and back of it is x * x
(5 * 5), so the from and back is 25 + 25 = 50.
The three long sides are x * y (5*20), so the three long rectangles are 100 * 3 = 300. The bottom shape is 350 in total.
Step 2.
The top two rectangles are w * y, (8 * 20) so the two top rectangles are 160 * 2 = 320.
The triangles are w * w / 2 (8 * 8/2) (64 / 2) (32), so the two triangles are 64.
We subtract x from z to get 6.3.
Then, we multiply 6.3 by 20. We get 126. Finally, we add all the values together to get our final answer.
350 + 384+126 = 860
Our answer is D: 860.
2(x − 5) = 30
2(x + 5) = 40
x + 2x = 30
3x − x = 45
Equation 2(x + 5) = 40 is true for the value x = 15. Therefore, option C is the correct answer.
Given that, x=15.
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
1) Put x=15 in 2(x + 3) = 40 and simplify
2(15+3)≠40
36≠40
2) Put x=15 in 2(x − 5) = 30 and simplify
2(15-5)≠30
20≠30
3) Put x=15 in 2(x + 5) = 40 and simplify
2(15 + 5) = 40
40=40
4) Put x=15 in x + 2x = 30 and simplify
15+2×15 ≠ 30
45 ≠ 30
5) Put x=15 in 3x − x = 45 and simplify
3×15 -15 ≠ 45
30 ≠ 45
Equation 2(x + 5) = 40 is true for the value x = 15. Therefore, option C is the correct answer.

After a down payment of $500, the Alvarez family has $1,500 left to pay for a car. They can divide this balance into 5 equal payments of $300 each.
The Alvarez family bought a car for $2,000 and made a down payment of $500. This means that the amount left to pay for the car, also known as the car's balance, is $1,500 ($2,000 minus $500 = $1,500). If the family wants to make 5 equal payments, we will divide that balance by the number of payments they want to make.
So, the calculation would be $1,500 divided by 5, which equals $300. Therefore, each equal payment would have to be $300 for the Alvarez family to pay for the balance of the car over 5 payments.

Answer:
6 movies
Step-by-step explanation:
45-30=15 spent on movies
divide the 15 by 2.5 to get 6.
$30+$2.50m=$45
where m is the amount of movies
Answer:
let he purchaseed x movies
30 + 2.5x = 45
or 2.5x = 15
x=15/2.5 =6
