(a) A number is not more than 21.
(b) A number is at least 5.
(c) A number is more than 3/.5

Please help and thank you if you do

Answer 1

(a) The inequality that represents the sentence "A number is not more than 21" is "n ≤ 21". This inequality uses the less than or equal to operator (≤) to indicate that the number is not greater than 21.

(b) The inequality that represents the sentence "A number is at least 5" is "n ≥ 5". This inequality uses the greater than or equal to operator (≥) to indicate that the number is 5 or greater.

(c) The inequality that represents the sentence "A number is more than 3/.5" is "n > 3/.5". This inequality uses the greater than operator (>) to indicate that the number is greater than 3/.5.
