help!!

Answer 1

For number one, you need to take the combined age and subtract 8 and then divide by 2.

Answer 2

Once you divide by two you add the 8 back to one of the 2 numbers and thats belinda age.

Answer 3

take tony's age = x
belinda's age = 2x+8
combined age = 56
solve for x u get tony's age and do 2x+8 u get belinda's

Answer 4

If you take the equation 30*.10 you get 3 then add 16*.25 you get 7.
7 is the total amount the money adds up to and there is exactly 46 dimes and quarters used.

Answer 5

Thats for number 3.
