Using the mean concept, the expression that gives the average of the low and high temperatures is:
(-3 + 8)/2.
<h3>What is the mean?</h3>
The mean of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.
In this problem, the two observations are -3 and 8, hence their average is given by:
(-3 + 8)/2.

Answer:
If there isn't a given value for b, then every one of them are wrong
Step-by-step explanation:
The angles are equal (alternate angles in parallel lines)
X + 86 = 80
X = 80 - 86 = -6
Try to use this rule and use those 2 given points——-
(-7,-19) (0,3)
