Answer:
His mom is 32.
Step-by-step explanation:
If Tommy is x years old then his mom is 4x years old.
Also x + 4x = 40 ( the sum of their ages is 40)
Solving for x:
5x = 40
x = 40/5 = 8.
So Tommy's mom is 8*4 = 32 .
Answer:
30
Step-by-step explanation
His mother is 30 because 40/4 = 10
Making Tommy 10
10+30=40
