Answer 3

Problem Analysis

We are given that when a 4-meter piece is cut from a ribbon, the remaining length is 5 meters more than what was cut. We need to determine the original length of the ribbon.

Solution

Let's assume the original length of the ribbon is x meters.

According to the given information, when a 4-meter piece is cut from the ribbon, the remaining length is 5 meters more than what was cut. This can be expressed as:

x - 4 = 4 + 5

Simplifying the equation:

x - 4 = 9

Adding 4 to both sides:

x = 13

Therefore, the original length of the ribbon was 13 meters.

The correct answer is 13.

Conclusion

The original length of the ribbon was 13 meters.
