Answer 2

Inequality with 6 as a Solution

To determine in which inequality the number 6 is a solution, let's examine the given inequalities:

1. 17 + x > 40 2. 8 + y < 11 3. 42 : t > 1 4. 49 - n < 39

Let's go through each inequality and check if 6 satisfies the condition.

1. 17 + x > 40: - To check if 6 is a solution, substitute 6 for x: - 17 + 6 = 23, which is not greater than 40. - Therefore, 6 is not a solution to this inequality.

2. 8 + y < 11: - To check if 6 is a solution, substitute 6 for y: - 8 + 6 = 14, which is not less than 11. - Therefore, 6 is not a solution to this inequality.

3. 42 : t > 1: - To check if 6 is a solution, substitute 6 for t: - 42 ÷ 6 = 7, which is greater than 1. - Therefore, 6 is a solution to this inequality.

4. 49 - n < 39: - To check if 6 is a solution, substitute 6 for n: - 49 - 6 = 43, which is not less than 39. - Therefore, 6 is not a solution to this inequality.

Based on the analysis above, the inequality in which the number 6 is a solution is 42 : t > 1.
