Which of the numbers 6,7, and 8 is a solution of 3x_< 18
To determine which of the numbers 6, 7, and 8 is a solution of the inequality 3x < 18, we substitute each number into the inequality and check if it holds true.
1. For x = 6:
3(6) < 18
18 < 18
This is not true, so 6 is not a solution.
2. For x = 7:
3(7) < 18
21 < 18
This is not true, so 7 is not a solution.
3. For x = 8:
3(8) < 18
24 < 18
This is also not true, so 8 is not a solution.
Therefore, none of the numbers 6, 7, and 8 are solutions to the inequality 3x < 18.
