Accepted Solution
A:
Answer: 3 dimesStep-by-step explanation:Let n represent the number of nickels and d represent the number of dimes Reese has in his pocket.Given system : [tex]n+d=11........(1)\\5n+10d=70............................(2)[/tex]Divide equation (2) by 3 on both sides, we get[tex]n+2d=14................................(3)[/tex]Subtract equation (1) from (3), we get[tex]d=3[/tex]Hence, there are 3 dimes in Reese's pocket.
