Answer: x less-than-or-equal-to 6

Explanation:

Hi, to answer this question we have to write an inequality with the information given:

The symbol for less-than-or-equal-to is.≤

5x -9 ≤21

Solving for x:

5x≤21+9

5x≤30

x≤ 30/5

x≤ 6

x less-than-or-equal-to 6 is the solution of the inequality.

Feel free to ask for more if needed or if you did not understand something.

Answer 2
