-13 to 0 = 13 degrees changed. 0 to 22 is 22 degrees changed. 13 + 22 = 35 degree change.
10-3 = 7.
So there was a change of 35 degrees across 7 hours
35/7 = 5 degrees per hour.
Yeah I think so you have to solve and break it down
Answer:

Step-by-step explanation:
Given:

Number line is from range -2 to 2 with all increment of ±
on both sides.
Step 1: First we will solve the equation we will get;

Step 2: Now we will try to make the denominator common so we will get;

Step 3: Now from the number line when we subtract 
from
we get number of spaces left are - 7
Hence now it will become:

Hence the final Answer is 
Answer: 30 (units)
Step-by-step explanation: |-7|+|23|=30
