Three times the sum of three consecutive integers is 72. What are the integers?

Sol'n:

3(x+x+1+x+2)=72

3x+3=24

3x=24-3

3x=21

x=7

x+1=8

x+2=9

thus the integers are: 7,8 & 9

Step-by-step explanation:

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
