The sum of the ages of Michael and Savannah is 114 years. 7 years ago, Michael's age was 4 times Savannah's age. How old is Michael now?

m = age of michael

s = age of savannah

m+s=114

7 years ago:

(m-7)=4(s-7)

m+s=114

m=4s-21

(4s-21)+s=114

5s=114+21=135

s=135/5=27

m=114-s=114-27=87

now michael is 87.

Savannah is 27

a = 3 b = 3 c = 5

Step-by-step explanation:

To divide you should turn the fractions into improper fractions making it 9/2 ÷ 5/4

Then using the keep change flip method you need to do 9/2 × 4/5

Next you multiply and should get 36/10 or 3 3/5

This means a = 3 b = 3 c = 5
