Question

Given, 115=1+6(5r+4), what is the value of 9r?

Answer 1

9r=27

Explanation:

• you first are gonna multiply 6 into the 5r+4
• then you are gonna have this: 115=1+30r+24
• then u add the 24 and 1 together
• you get 115=30r+25
• then you subbtract 25 from both sides
• you get 90=30r
• then you didvide 30 by both sides
• you get 3=r
• so now we multiply 9 cause we need the value of 9r and r=3
• 3*9=27
