First you must add up all of the numbers. Then divide the sum by the number of students in the class. You will get 2.65 as your answer. Then round to the nearest number. Your final answer is 3.
Answer:
Step-by-step explanation:
Recall that we say that d | a if there exists an integer k for which a = dk. So, let d = gcd(a,b) and let x, y be integers. Let t = ax+by.
We know that
so there exists integers k,m such that a = kd and b = md. Then,
. Recall that since k, x, m, y are integers, then (kx+my) is also an integer. This proves that d | t.

The equation 25x+1295=212000 models the situation. The bill had charges of 8428.2 minutes
Step-by-step explanation:
Given,
Monthly rate = $1295
Per minute charges = $25
Bill for x minutes = $212000
As x are the total minutes.
Per minute charges * Total minutes + Monthly rate = Bill for x minutes
25x+1295=212000

Dividing both sides by 25

The equation 25x+1295=212000 models the situation. The bill had charges of 8428.2 minutes
