The coordinates of the midpoint are the average of the coordinates of the given points.
So, the x coordinate of the midpoint is the average of the x coordinates of the given point:

And similarly, the y coordinate of the midpoint is the average of the y coordinates of the given point:

So, the midpoint is the point

I did the work on paper:
Answer:
-7>t
Step-by-step explanation:
If the temperature is lower than -7 degrees Fahrenheit, then the inequality must show a number less than -7. Or in other words, -7 is greater than what the temperature is, thus the answer is -7>t
3 hours
You can turn this into an equation:
F = 26 + 31t
Where F is the money Ralph earned, and t is the number of hours he worked.
Plugging in the 119 for F, we get
119 = 26 + 31t
93 = 31t
3 = t
