Mrs. Hodges has $60 to spend on classroom materials. She buys some whiteboard markers for $18 and a textbook for $24. She also bought two posters for her walls. The posters were both the same price. Solve the equation 2 p + 42 = 60 2p+42=60 to find the price of each poster.

the answer is 40.

proof:

it would have to be 3/0

1875cm³

step-by-step explanation:

we have a 20 × 20 × 5 container with (what im guessing is a) 5 × 5 × 5 hole in the center. first, we need to calculate the volume of the 20 × 20 × 5 container.

20 × 20 × 5 = 2000cm³

now, we need to calculate the volume of the hole.

5 × 5 × 5 = 125cm³

now to find the area of the container, we take to solid area of the container, and subtract the area of the hole.

2000cm³ - 125cm³ = 1875cm³
