Respuesta :

To find the value of x, you need to set up a proportion.This is the proportion you would set up:

2.5                    x
----       =        ------
3.75                60

x=40
Okay so.
When you take 60 from the enlarged picture and divide it from the original (3.75), you get 16.
You're trying to find X, not the amount it took to multiply to get to 60 by dividing it by 3.75.
So answer choice A will be eliminated.
Answer choice D will be eliminated also because 90 is bigger than 60, and the side with 60 is bigger than the X side.


So, when you take the 16 and multiply it by 2.5 you get 40.
 I believe your answer to be answer choice B.
