If Gary lost 17 pounds and gained 8 pound back, then we have
-17 pounds + 8 pounds = -9 pounds.
Therefore the additive inverse of the change in Gary's weight is 9 pounds.
That is, Gary lost 9 pounds of weight.
The nearest tenth would be the first decimal place, so the answer would be 23.8
The length of the line is the difference between the endpoints of the line
The length of each line to the nearest fourth inch is 0.25 inch
<h3>How to measure the length of each line</h3>
The length of the horizontal line is given as:
Length = 2 inches
This is calculated as:
Length = 3 inches - 1 inch
Length = 2 inches
8 lines are to be drawn between the 1 inch and 3 inches point.
So, the length (l) of each line is:

Simplify the fraction

Divide

Hence, the length of each line to the nearest fourth inch is 0.25 inch
