Answer:


Step-by-step explanation:

5) By midpoint theorem of triangles we get

2x=2(31) or x=31

8) By mid point theorem for triangles we get

6x+11=2(2x+23)

6x-4x=46-11

2x=33

x=16.5

Also since mid point bisects a side we get

2y+6=3y-9

y=15

9)By mid point theorem for triangles we get

x=2(25)=50

10)By mid point theorem for triangles we get

3x-6 =2x:  2x=2y+1

x=6:  12=2y+1

x=6 and y =5.5
