Ann's age after h years is 2h
Bill's age after h years is 3h
Charles' age after h years is 8 + h
The sum of their ages after h years is 6h + 8
Step-by-step explanation:
The given is:
Anne is currently h years old
Bill is currently 2h years old
Charles is currently eight years old
We need to find an expression for each person’s age after h years and then find an expression for the sum of their ages after h years
∵ Ann is h years old now
∵ Her age after h years = her age now + h
∴ Her age after h years = h + h
∴ Her age after h years = 2h
Ann's age after h years is 2h
∵ Bill is 2h years old now
∵ His age after h years = his age now + h
∴ His age after h years = 2h + h
∴ His age after h years = 3h
Bill's age after h years is 3h
∵ Charles is 8 years old now
∵ His age after h years = his age now + h
∴ His age after h years = 8 + h
∴ His age after h years = 8 + h
Charles' age after h years is 8 + h
Add their ages after h years
∵ The sum of their ages after 8 years = 2h + 3h + 8 + h
- Add like terms
∴ The sum of their ages after 8 years = (2h + 3h + h ) + 8
∴ The sum of their ages after 8 years = 6h + b
The sum of their ages after h years is 6h + 8
