Answer:
x < 8
Step-by-step explanation:
All you need to do is solve the inequality for x, by moving 4 to the right side as I have shown below:
x + 4 < 12
x + 4 - 4 < 12 - 4
For mean it's the average. You add all three numbers (13, 13 , 10), then you divide it by three since their are three numbers. Average would be 12.
Hope this helps (:

Just add
2. can not be 3 bc it would 5
x=3.5
Why?
14/4=3.5
