So let’s say you have (2,8) and (4,12)
Your x values are your first ones. So 2 and 4.
that formula is to find the midpoint so let 2 by x1 and 4 be x2. Add those together you get 6. Then divide by 2. Always by 2. You get 3. That’s the midpoint of those two points. Same thing for the y values.

Answer:4 runners finished the race
Step-by-step explanation:
There were 60 runners to start a race.
In the first half of the race, 2/3 of them dropped out. This means that the number of runners that dropped out would be
2/3 × 60 = 40 runners
The number of runners that is left out would be
60 - 40 = 20
In the second half of the race, 4/5 of the remaining runners dropped out. This means that the number of runners that dropped out would be
4/5 × 20 = 16 runners
Therefore the number of runners left and also finished the race would be
20 - 16 = 4
4 runners finished the race
