Answer:
Your(my) number is 40
Step-by-step explanation:
I. Given 80/something, + 13, * 5 = 75 when x is something
So [ [tex]\frac{80}{x}[/tex] + 13 ]5 = 75
[ [tex]\frac{400}{x}[/tex] + 65] = 75
[tex]\frac{400}{x}[/tex] = 75 - 65
[tex]\frac{400}{x}[/tex] = 10
400 = 10x
x = 40
II. Prove by replace 40 in x
[(80/40) + 13]5 = 75
[2 + 13] 5 = 75
(15)5 = 75
75 = 75 true
