{y=x+29x+y=4.7

{x=29−yx+y=4.7

{x+y=4.70.1x+0.25y=29

Answer 1

x+y=29

0.1x+0.25y=4.7

Explanation:

- x+y=29 (x is the number of dimes and y is the number of quarters. there is a total of 29 coins)

- Each dime is $0.1 and each quarter is $0.25.

- By multiplying the number of dimes by $0.1 and multiplying the number of quarters by $0.25, you will get the total amount of money, which is $4.7. - - Therefore, the answer is:

x+y=29

0.1x+0.25y=4.7
