Answer:

I got 9.

Step - By - Step Explanation:

7x - 13 = 5x + 5

7x = 5x + 18

2x = 18

x = 18 ÷ 2 = 9

x = 9

58
7(x) - 13 = 5(x) + 5
7x - 91 = 5x + 25
7x - 5x - 91 = 25
2x - 91 = 25
2x = 25 + 91
2x = 116
x = 58

C. 20% because 15 goes into 75 5 times, and to find the percentage you would divide 100 by that number, 5, to get 20. So he has gone 20%
