Which of the numbers 6, 7, and 8 is a solution of 3x≤18 ?(1 point)

Answer 1

To find out which number is a solution of the inequality 3x ≤ 18, we can substitute each number into the inequality and see if the inequality holds true.

Let's start with 6:
3(6) ≤ 18
18 ≤ 18
This inequality is true, so 6 is a solution.

Let's move on to 7:
3(7) ≤ 18
21 ≤ 18
This inequality is not true, so 7 is not a solution.

Finally, let's try 8:
3(8) ≤ 18
24 ≤ 18
This inequality is not true, so 8 is not a solution.

Therefore, the only number that is a solution of 3x ≤ 18 is 6.
