C. d-11 > 27; d > 38
d+11 ≥ 27; d ≥ 49

Answer 1

Explanation:

To translate English sentences into inequalities, we need to recognize the phrases that indicate the inequality. Think about the phrase ‘at least’ – what does it mean to be ‘at least 21 years old’? It means 21 or more. The phrase ‘at least’ is the same as ‘greater than or equal to’.

Answer: A. d - 11 ≥ 27, d ≥ 38
