Half of a number n is at most 5 units from 14(write the absolute value inequality)

18≤n≤38 is absolute value inequality for the problem.

Step-by-step explanation:

Given situation:- Half of a number n is at most 5 units from 14

that means the difference between 14 and half times n is less than 5

⇒18≤n≤38 is absolute value inequality for the problem.

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
