Answer with Step-by-step explanation:
We are given that point B lies on the segment AC.
Length of AC= a cm
We have to find the the distance between the midpoint of segment AB and BC.
When B lies on the segment AC.
Let mid point of segment AB and BC are E and F.
E is the midpoint of segment AB.
Therefore, 
Distance between E and F is given by
Hence, the distance between the midpoints of segment AB and BC is given by

Answer:
Step-by-step explanation:
Step 1: Subtract 3x from both sides.
5x−4−3x=3x+18−3x
2x−4=18
Step 2: Add 4 to both sides.
2x−4+4=18+4
2x=22
Step 3: Divide both sides by 2
2x/2= 22/2
x= 11
