Here are the sorted items based on the inequality descriptions and solutions:
- M is at most 7 - This corresponds to the inequality M ≤ 7.
- m is at least 7 - This corresponds to the inequality m ≥ 7.
- m is greater than 7 - This corresponds to the inequality m > 7.
- m is less than 7 - This corresponds to the inequality m < 7.
