Points a (12.85) and b (125.3) are marked on the coordinate ray. Point C is marked between points A

Points a (12.85) and b (125.3) are marked on the coordinate ray. Point C is marked between points A and B. Find AB, AC and BC if it is known that AC is 2.85 more than CB

1. Find the length of the segment AB, for this we subtract the coordinate of point A from the coordinate of point B:

125.3 – 12.85 = 112.45.

2. Denote by the unknown variable x – the length of the segment AC,

Then x – 2.85 – the length of the segment СB.

Let’s make the equation:

x + x – 2.85 = 112.45;

2x = 115.3;

x = 57.65 – the length of the AC segment,

57.65 – 2.85 = 54.8 is the length of the segment СB.

Answer: AB = 112.45, AC = 57.65, CB = 54.8.
