Question

I need help with b and c please it's due tomorrow and can you tell me how I could solve it

Answer 1

Answers:
b.) 648,000
c.) I can't tell because I think you are missing some of the equation

Step-by-step explanation:
7,200 ÷ n = 90
To find n, you have to multiply both sides by 7,200
7,200 • 7,200 ÷ n = 7,200 • 90
n = 648,000

Answer 2

7,200x90=n and then that answer divided by 90 and then n equals your answer
