Points C, D, E lie on the straight line k. When measuring, it turned out that CD = 6 cm

Points C, D, E lie on the straight line k. When measuring, it turned out that CD = 6 cm, and DE = 4 cm. Determine the distance between points C and E.

Given:
straight line k,
points C, D, E belong to line k,
CD = 6 centimeters,
DE = 4 centimeters.
Find the length is the distance between points C and E, that is, the length of the segment CE -?
Decision:
Consider the segment CE. Its length consists of the sum of the lengths of the segments CD and DE, that is:
CE = CD + DE.
Since CD = 6 centimeters and DE = 4 centimeters, then
CE = 6 centimeters + 4 centimeters;
CE = 10 centimeters.
Answer: The length of the CE segment is 10 centimeters.
