Answer:
Step-by-step explanation:
Let x = to the number of nickels.
Let x + 7 = the number of quarters.
So multiply x by .05 to find out how much the nickles are worth and
multiply x + 7 by .25 to find out how much the quarters are worth.
Then add them together to get the total and solve.
.05x + .25(x + 7) = 2.65
.05x + .25x + 1.75 = 2.65
.30x + 1.75 = 2.65
Subtract 1.75 from each side of the equation.
.30x = .90
x = 3
x + 7 = 10
So 10 is the number of quarters.
Answer:
Step-by-step explanation:
we only have to have 7 more quarters than nickels.. so put one nickel and 8 quarters

6 dimes
8 quarters
