The sum of the lengths of the two segments is 75 cm. The length of the second segment is 4 times

The sum of the lengths of the two segments is 75 cm. The length of the second segment is 4 times longer than the first. Find the length of the first segment.

1) Find out how long the first segment has, if it is known that the sum of the lengths of the two segments is 75 cm, and the second side is 4 times longer than the first side. We draw up an equation according to the condition, where:

X is the length of the first part;

4X is the length of the second part;

75 is the total length.

X + 4X = 75;

5X = 75;

X = 75/5;

X = 15 cm.

Answer: the length of the first segment was 15 cm.
