N + (n + 2) ≥ 80
n + n + 2 ≥ 80
2x + 2 ≥ 80
- 2 - 2
2x ≥ 78
2 2
x ≥ 39
The answer is A.
7.40 x 2 + .98= 15.78 if she pays with $20 than her change will be $4.22

Answer:
5^3*5^-7 = 1/5^4 b. is true = 625
5^3*5^-7 = 5^-4 c. is true = 625
Step-by-step explanation:
b. Left hand side
Simplify the following:
5^3/5^7
Combine powers. 5^3/5^7 = 5^(3 - 7):
5^(3 - 7)
3 - 7 = -4:
5^(-4)
5^4 = (5^2)^2:
1/(5^2)^2
5^2 = 25:
1/25^2
