1/x^-7
It would look more like 1
------
-7 (as an exponent)
x
It would be 6x + 6y as the final expansion
For this case, the first thing we must do is define variables.
We have then:
d: number of dimes
q: number of quarters
We now write the system of equations that models the problem.
We have then:
He has a total of 30 coins:

The toal value of Kyles coins is $ 4.80:

Answer:
A system of equations that can be used to find the number of dimes, d, and the number of quarters, q, kyes has is:


Answer:
C = 35 pi
Step-by-step explanation:
The new diameter is 5 + 30 = 35
The circumference = pi * d
The circumference = 35*pi
