| 1. Let’s denote the length of the segment XY through x.
2. Determine the length of the segment YZ:
3/5 * x = 0.6x.
3. The length of the segment XZ is equal to the sum of the lengths of the segments into which it is divided by the point Y, that is, XZ = XY + YZ.
Let’s compose and solve the equation:
0.6x + x = 24;
1.6 x = 24;
x = 24: 1.6;
x = 15.
4. The length of the XY segment is 15 cm.
Answer: The length of the XY segment is 15 cm.
