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: 76
Answer:
Step-by-step explanation:
Combine like terms
7x^6
2x^5+5x^5= 7x^5
8x^3
-3x^2-6x^2= -9x^2
9x+2x= 11x
-5
Put back into order
7x^6+7x^5+8x^3-9x^2+11x-5
