Answer 1

138 в первом
Во втором и третьем 138-29=109
В трех мотках 138+109=247

Answer 2

Problem Analysis

We are given that there is a total of 138 meters of rope in one bundle, which is 29 meters more than the combined length of the first and second bundles. We need to determine the length of the three bundles.

Solution

Let's assume the length of the first bundle is x meters.

According to the problem, the length of the second bundle is also x meters.

The total length of the first and second bundles combined is then 2x meters.

We are given that the total length of the three bundles is 138 meters, which is 29 meters more than the combined length of the first and second bundles.

Therefore, we can set up the following equation:

2x + 29 = 138

To find the value of x, we can solve this equation:

2x = 138 - 29

2x = 109

x = 109 / 2

x = 54.5

So, the length of each of the first and second bundles is 54.5 meters.

To find the length of the third bundle, we can subtract the combined length of the first and second bundles from the total length of the three bundles:

Length of third bundle = Total length - Combined length of first and second bundles

Length of third bundle = 138 - (2 * 54.5)

Length of third bundle = 138 - 109

Length of third bundle = 29 meters

Therefore, the lengths of the three bundles are 54.5 meters, 54.5 meters, and 29 meters.
