Ten less than twice a number is equal to at least 52. What are all the possible values of the number? Write an inequality that could be used to solve this problem. Use the letter a as the variable, and write the inequality so that the a term comes first. Do not solve the inequality.

The inequality that could be used to solve this problem is:

2a - 10 ≥ 52

The possible values of the number (a) would be any value that satisfies this inequality.
