Answer:

29 dimes

Step-by-step explanation:

Let D represent dimes and the nickels as N.

We know that there are a total of 64 coins, so D + N = 64. The total of our coins is $5.15, since each dime is worth 10 cents and each nickel is worth 5 cents, we can display it as 10D + 5N = 515. Now, we can set up a system of equations as shown

D + N = 64

10D + 5N = 515

the solutions to the equations are D=29 and N=35

Hope this helps!
