Answer:
Your answer: 5.(4,-4)
Step-by-step explanation:
Please mark brainliest and have a nice night/day!!
The average has to be at least 120 and at most 130
To calculate the average we need the sum of all values divided by the number of values, in this case, three (135, 145 and the third result).
120 ≤ (135 + 145 + n)/3 ≤ 130
In inequalities like this, what we change in one side, must be changed in the othe rside as well.
360 ≤ 280 + n ≤ 390
80 ≤ n ≤ 110
Me toooo! if anyone in these comments could answer my question, that'd be awesome!
