Answer:
\(x\geq 90\).
Step-by-step explanation:
Let x represent the number.
We have been given a sentence. We are supposed to translate our given sentence into an inequality.
We are told that the number is at-least 90. This means that our required number is greater than on equal to 90.
We can represent this information in an inequality as:
\(x\geq 90\)
Therefore, our required inequality would be \(x\geq 90\).
