Dan has twice as many stickers as Cam does. If Dan gives Cam 15 of his stickers he will still have 22 more than Cam. How many stickers does each boy have?

Answers

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 answer is 60 since the other shape has same answer for that side

Answer: x=60

Step-by-step explanation:

Hey! X would be 60 because the diagram on the left has proportions of 6/6. The diagram on the right has a porportion of x/60. We want the proportions to be equal so it has to be 60!

6/6 = 1

60/60 = 1 (they are now equal and have equal proportions!)
