12.5 To find the average of a group of numbers, add all the numbers together and divide the sum by the number of numbers that were added together. Example: 5 + 10 + 15 + 20 = 50. Divide the sum (50) by 4 (you added four numbers together to get the sum): 50 divided by 4 = 12.5
The sum is 328.
N + 15
x+15
five times the sum of a number and 8 is -15.
2*(15 + N)
