Answer:
15 dimes
Explanation:
The equation 4/5d - 5 = 3/5d - 2 Represents the number of dimes, d, in a stack how many dimes are in the stack?
You are asked to solve for d:
4/5d - 5 = 3/5d - 2
subtract 3/5d from both sides:
4/5d - 5 - 3/5d = 3/5d - 2 - 3/5d
1/5d - 5 = -2
add 5 to both sides:
1/5d - 5 + 5 = -2 + 5
1/5d = 3
multiply both sides by 5:
5(1/5d) = 3(5)
d = 15
