Answer 3

what is the average a number of integers?

Answer 4

its 38

Answer 5

no, i mean let's say you're given integers a, b, c, d, e, f. How do you find their average?

Answer 6

oh you add them all together and then divide by the amount

Answer 7

yes, let's say when we add up all those integers, we get a certain number, x. So this means:
x/6 = 38

Answer 8

that means the sum itself is x = 38*6 = 228

Answer 9

Are you following so far?

Answer 10

yes, im following

Answer 11

so now when we add another number, the total sum is the sum of the first 6 numbers plus the 7th number, so 228+y

Answer 12

to find the average we need to divide that total sum by 7:
(228+y)/7, and that equals 47

Answer 13

(228+y)/7 = 47
Find y.
