Answer 2

Length of the Segment

The length of the segment is given as 9 cm.

Finding One-Third of the Segment

To find one-third of the segment, we divide the length of the segment by 3. Therefore, one-third of a segment with a length of 9 cm is 3 cm.

Formulating an Inverse Problem

To formulate an inverse problem, we need to create a scenario where the given information is the solution. In this case, the given information is that one-third of a segment is 3 cm.

Let's say we have a segment divided into three equal parts, and one of those parts is 3 cm. We can represent the length of each part as x. Therefore, the length of the entire segment would be 3x.

So, the inverse problem can be stated as follows: "If one-third of a segment is 3 cm, what is the length of the entire segment?"

To solve this problem, we can set up the equation:

3x = 9

By solving this equation, we can find the value of x and determine the length of the entire segment.

Solving the Inverse Problem

To solve the equation 3x = 9, we divide both sides of the equation by 3:

x = 9 / 3

Simplifying the equation, we find:

x = 3

Therefore, the length of each part of the segment is 3 cm, and the length of the entire segment is 3 x 3 = 9 cm.

So, the solution to the inverse problem is that if one-third of a segment is 3 cm, then the length of the entire segment is also 9 cm.
