Answer:
Answer is D
Step-by-step explanation:
Given:
mother's age = 3x - 3
daughter's age = x
total of their ages = 45
Mother's age + daughter's age = 45
3x - 3 + x = 45
4x = 45 + 3
4x = 48
4x/4 = 48/4
x = 12 daughter's age. CHOICE B.
mother's age : 3x - 3 = 3(12) - 3 = 36 - 3 = 33
To check:
mother's age + daughter's age = 45
33 + 12 = 45
45 = 45
