Answer:
nickels- 5, quarters- 11
Step-by-step explanation:
nickel= 5 p, quarter= 25 p
5x+25(x+6)= 300
30x+150=300
30x=150
x=150/30
x=5 nickels
x+6= 11 quarters
I am assuming the -3 is an exponent.
y⁻³ and 5⁻³
If the exponent is a negative number, it simply means that the number is a denominator with 1 as the numerator.
y⁻³ is 1/y³
5⁻³ is 1/5³ = 1/125
The number is still raised to its exponential power but its placement is different.
5³ would be 125 or 125/1. It would be the numerator with 1 as the denominator.
