Answer:
x=16
Step-by-step explanation:
- Just divide it as a decimal (40/2.5)
I’m just guessing but since 13/4=3.25 that means that the triangle dialated by 3.25 so you multiply 8 by 3.25 and X might be 26
75 books because you multiply 3 x 25 . When you do that you get 75. So the answer to the question would be 75.
