Points A B and C lie on the same straight line find the length of the segment B C if AB = 2.7 cm AC = 6.4 cm how many solutions does the problem have?

The problem has 2 ways of solving.

Method 1:

Let point A lie between points B and C, then the length of the segment BC is equal to the sum of the lengths of the segments AB and AC:

BC = AB + AC = 2.7 + 6.4 = 9.1 cm.

Answer: the length of the BC segment is 9.1 cm.

Method 2:

Let point B lie between points A and C, then the length of the segment BC is equal to the difference between the segments AC and AB:

BC = AC – AB = 6.4 – 2.7 = 3.7 cm.

Answer: The length of the BC segment is 3.7 cm.
