Hope this helps!
Answer:
first one: 3 1/3 = 7/3 second: 2 3/4 = 11/4
third one: 3 1/3 + 2 3/4 = 10/3 + 11/4 = 40/12 + 44/12
there fore the answer is: 84/12 or 7
this may help you the first one question only.
Answer:
![\left(\dfrac{x_E+x_F}{2},\dfrac{y_E+y_F}{2}\right).](https://tex.z-dn.net/?f=%5Cleft%28%5Cdfrac%7Bx_E%2Bx_F%7D%7B2%7D%2C%5Cdfrac%7By_E%2By_F%7D%7B2%7D%5Cright%29.)
Step-by-step explanation:
Let points D, E and F have coordinates
and ![(x_F,y_F).](https://tex.z-dn.net/?f=%28x_F%2Cy_F%29.)
1. Midpoint M of segment DF has coordinates
![\left(\dfrac{x_D+x_F}{2},\dfrac{y_D+y_F}{2}\right).](https://tex.z-dn.net/?f=%5Cleft%28%5Cdfrac%7Bx_D%2Bx_F%7D%7B2%7D%2C%5Cdfrac%7By_D%2By_F%7D%7B2%7D%5Cright%29.)
2. Midpoint N of segment EF has coordinates
![\left(\dfrac{x_E+x_F}{2},\dfrac{y_E+y_F}{2}\right).](https://tex.z-dn.net/?f=%5Cleft%28%5Cdfrac%7Bx_E%2Bx_F%7D%7B2%7D%2C%5Cdfrac%7By_E%2By_F%7D%7B2%7D%5Cright%29.)
3. By the triangle midline theorem, midline MN is parallel to the side DE of the triangle DEF, then points M and N are endpoints of the midsegment for DEF that is parallel to DE.
