Point B lies on segment AC , which has length a centimeters. Find the distance between the midpoints of segments AB and BC . NO explanation needed. I need this fast

The correct answer is - EF= a/2

Step-by-step explanation:

Given:

point B lies on the segment AC.

Length of AC= a cm

solution-

When B lies on the segment AC.

Let the midpoint of segment AB and BC are E and F.

E is the midpoint of segment AB.

Therefore, AE= EB

BF = FC

So, AC = AE+EB+BF+FC

or, AC= EB+EB+BF+BF

a = 2 (EB+BF), or, a/2 = EB+BF

Distance between E and F is given by

EF = EB+BF, then

EF = a/2

Hence, the correct answer is - EF= a/2

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

gdp is the best phrase!
