kumpel [21]2 years ago
8 0
Estimation for addition: 86 rounds up to 90 and 17 rounds up to 20 so:
90 + 20 = 110
Estimation for subtraction is the same thing but with subtraction
90 - 20 = 70

Now for the exact answers:
86 + 17 = 103
86 - 17 = 69

Your answers are 110, 70, 103, and 69.

Mom is 60 years old and daughter is half mom's age. How old was daughter when mom was 4 times her age?
rewona [7]

Answer:

  10 years old

Step-by-step explanation:

The difference in ages is 60 -30 = 30 years. When mom was 4 times daughter's age, the difference in their ages was 3 times the daughter's age.

The age difference was 30 years at that time, so the daughter was 10 years old.
