Answer:
915
Step-by-step explanation:
N+d=34
.05n+.10d=2.60
Solve by substitution
n=34-d
.05(34-d)+.10d=2.60
1.7-.05d+.10d=2.60
.05d=.90
d=18 dimes
18+n=34
n=16 nickles
You have to take the x to on side and numbers to the other but in order to do that you'll have to divide -3 from both sides and then just solve the equation.
A cause she measured the side of it
4/8, 5/10, 10/20/ and 2/4
It's just half of it, like half of 20=10
and half of 8=4
