To find the solution of the inequality c > 5, we need to look for numbers that are greater than 5 on the number line. Let's analyze the given numbers:
1. 2: This number is less than 5, so it is not a solution to the inequality c > 5.
2. 2.5: This number is also less than 5, so it is not a solution to the inequality.
3. 5: In the inequality c > 5, the sign is ">" which means "greater than," not "greater than or equal to." Therefore, 5 is not included in the solutions as it is not strictly greater than 5.
4. 6.5: This number is greater than 5, so it is a solution to the inequality c > 5.
Therefore, the number 6.5 is a solution to the inequality c > 5 as it satisfies the condition of being greater than 5 on the number line.
