Answer:
If we are working in a coordinate plane where the endpoints has the coordinates (x1,y1) and (x2,y2) then the midpoint coordinates is found by using the following formula:
midpoint=(x1+x22,y1+y22)
Step-by-step explanation:
18 would be the right answer
I think it's the second answer...
The answer would be 2.2.
This sentence as an expression would be n - (-3n) = n + 11.
Solve it and you'll get 2.2!
