15 ?x

x=3

therfore w=20

Answer 2

W = 3

The large backpack is 25 and the small is 5. Using proportional reasoning, and since they say the backpacks are the similar, we can find the change. 25/5 would equal 5. So, 15/5, what you do to one side you must do to the other, would equal 3. W = 3.

Hope this helps!!
