N.Edwards in Mr.Kirkland's Math III Class
The Johnson twins were born 13 years after their older sister.This year, the product of the three siblings' ages is exactly 653 more than the sum of their ages. How old are the twins?
Since the oldest sister is thirteen years older than the twins, here is an example of how old they would be if the twins were 3,4, and/or 5. ( T+13=S)
This year, the product of the three siblings ages is exactly 653 more than the sum of their ages. This work shows that the twins are 6 years old.
Type in a calculator T^3+13T^2-3T-653 and you will come up to your answer once your round and the twins are 6.
