every similar line means that they have the same value
x=8
y=10
go look for a way to find the last side in the small rectangle that has x and y
15%=3
5%=1
5(20)=100
1(20)=20
So, there are 20 students in the class.
Answer:
number of dimes is 8
number of quarters is 15
Step-by-step explanation:
let 'd' = number of dimes
let 'd+7' = number of quarters
.10d + .25(d + 7) = 4.55
.10d + .25d + 1.75 = 4.55
.35d = 2.80
d = 8
q = 7 + 8
