C.

Step-by-step explanation:

First, recognize the fact that he has a total of 4 boxes, with only 8 different colored crayons inside. Next, you should see that each colored crayon can be found in the box 5 times, or there is 5 of the same crayon. Saying this, you know that the total amount of crayons would be 5 x 8, correct. Okay, so now, you will want to understand that he has 4 boxes, so you will multiply 4 x 40 (from the 5 x 8), which can be seen as 4 x 5 x 8 = c.

Hope this helps! :)

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9
