Answer:
2,-1.5
Step-by-step explanation:
To find the midpoint of a line segment, take the average of the x coordinates and y coordinates of the two points that make it up.
![\frac{2+2}{2} ,\frac{4+(-7)}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2%2B2%7D%7B2%7D%20%2C%5Cfrac%7B4%2B%28-7%29%7D%7B2%7D)
=![\frac{4}{2} , \frac{-3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B2%7D%20%2C%20%5Cfrac%7B-3%7D%7B2%7D)
![\frac{4}{2} , \frac{-3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B2%7D%20%2C%20%5Cfrac%7B-3%7D%7B2%7D)
=2,-1.5
The answer is
-10=-15+5x
x = 1
You can't change the sum by changing the grouping. Any way you cut it, you will always get 226, as you only have addition operations, and the commutative property [a+(b+c)=(a+b)+c] means that the sum will always be the same.
