For this case, the first thing we must do is define variables:
x: number of quarters
y: number of nickels
We now write the system of equations:
x + y = 68
0.25x + 0.05y = 13.40
Solving the system we have:
x = 50
y = 18
Answer:
they have:
quarters = 50
nickels = 18
Answer: It is Geometric.
Step-by-step explanation: Because it does not have a fixed pattern that adds or subtract which arithmetic does.
3x+2(5x-3)=7
3x+10x-6=7
13x-6=7
13x=13
x=1
500 − 250 = 250 pieces left after donation
Yolanda got 180 pieces....then Enrique got 70 pieces
So he got 70 /250 = 7/25 = 28% of the remaining candy
Answer:
Yes they are the same
