Answer:
C. Elise should multiply both sides by 8.
Step-by-step explanation:
We need to undo what is being done to x
We are dividing x by 8, so to undo it we do the opposite.
The opposite of dividing is multiplication.
We multiply each side of the equation by 8
You can solve this question by setting up an equation. Dan has twice as many stickers as Cam does. We can call Dan 2x, and Cam x. So the equation would be:
2x-15=x+22.
Then solve this equation:
Add 15 on both sides
2x=x+37
Subtract x on both sides
2x-x=37
X=37.
Therefore Cam has 37 stickers, and Dan has 74 stickers.
The area of the wall is figured by length * width.
Area of wall = 13*9=117 square feet
Since one can covers only 50 square feet you will not have enough with one can. You will need 117/50=2.34 cans. Assuming you can only buy full cans you would need to buy 3 cans.
