5^5 mod 7 = 3
5^4 mod 7 = 2
5^3 mod 7 = 6
3 -2 +6 mod 7 = 0
Therefore, 5^5 -5^4 +5^3 mod 7 = 0 and that sum is divisible by 7.
Answer:
the answer should be B -3
Step-by-step explanation:

Answer:
1/125, 1/625, 1/3125
Step-by-step explanation:
a8=25*(1/5)^7=25/78125=1/3125
I believe the answer is B: 3 + 7 + (-10).
The equation that models the difference in the projected enrollments for
public schools and private schools as a function of the number of years
since 1985 is B - R = (-18.53t^2 + 975.8t + 48140) - (80.8t + 8049) = -18.53t^2 + 975.8t + 48140 - 80.8t - 8049 = -18.53t^2 + 895t + 40091
