Question

Maria has three children. there are two age diffrence between each child . the total ages of all three is 36 years. rosa is the youngest how old is rosa

Answer 1

I think 8 years old

Explanation:

because if you do 8+9+19

you get 36. hope this helps

Answer 2

r = Rosa's age
r + 2 = next child
r + 4 = eldest child

r + (r + 2) + (r + 4) = 36

*Substitute '1' for the Rs

1r + 1r + 1r + 2 + 4 = 36

3r + 6 = 36

*Subtract '6' to both sides

3r + 6 - 6 = 36 - 6

3r = 30

*Divide '3' to both sides


`(3r)/(3) = (30)/(3)`

r = 10

Rosa is 10 years old.
