Applying the segment addition postulate:

x = 2.75

AB = 6x = 6(2.75) = 16.5 units

BC = 8x + 1/4 = 8(2.75) + 1/4 = 22.25 units.

What is the Segment Addition Postulate?

Based on the segment addition postulate, since B lies between points A and C on a line segment, then:

AB + BC = AC

AC = 38 3/4

AB = 6x

BC = 8x + 1/4

Substitute

6x + 8x + 1/4 = 38 3/4 [segment addition postulate]

14x + 1/4 = 155/4

14x = 155/4 - 1/4

14x = (155 - 1)/4

14x = 154/4

14x × 4 = 154

56x = 154

x = 154/56

x = 2.75

AB = 6x = 6(2.75) = 16.5 units

BC = 8x + 1/4 = 8(2.75) + 1/4 = 22.25 units.
