Point A is located on a straight line between points B and C. The length of segment CB is 3 cm longer than the length of segment AC. Find the length of line segment AB.
point A lies between points B and C,
BC = AC + 3 centimeters.
Find the length of the segment BA -?
Consider the BC segment. It consists of segments BA and AC, that is, the length of the segment BC = AB + AC.
According to the condition of the problem of the lengths of the segment BC = AC + 3, we substitute this expression in BC = AB + AC and get:
AB + AC = AC + 3;
AB = AC + 3 – AC;
AB = AC – AC + 3;
AB = 0 + 3;
AB = 3 centimeters.
Answer: 3 centimeters.
