Problem Analysis

We are given the information that Ruslan completed 14 exercises, Andrey completed -9 exercises, and Sergey completed as many exercises as Ruslan and Andrey combined. We need to determine how many exercises Sergey completed.

Solution

To find out how many exercises Sergey completed, we need to add the number of exercises completed by Ruslan and Andrey and then take the absolute value of the sum.

Let's calculate it step by step:

1. Ruslan completed 14 exercises. 2. Andrey completed -9 exercises. 3. Sergey completed as many exercises as Ruslan and Andrey combined.

To find out how many exercises Sergey completed, we can add the number of exercises completed by Ruslan and Andrey:

14 + (-9) = 5

The sum is 5. However, we need to take the absolute value of the sum since the number of exercises cannot be negative. Therefore, Sergey completed 5 exercises.

Answer

Sergey completed 5 exercises.
