Question

Tonya is twice Kevin's age in 3 years, tonya will be 17 . How old is kevin

Answer 1

Let tonya = T
Let Kevin = K

1) T = 2K (Tonya is twice Kevin)
2) T+3 = 17 (Tonya's age + 3 = 17)
T = 17-3 = 14.

Now from 1), T = 2K.
We know T = 14, so:
14 = 2K
K = 14/2 = 7

C. 7. is the answer

Answer 2

hope this helps
