Question

Write the inequality that represents the sentence below. Twice a number is at least 15

Answer 1

I know this has been answered, but i still want to explain it, if you wanted help

2n ≥ 15

work:

extract the elements of the problem.

Twice a number (we will use 2n because we don't know the number)
at least 15 (≥ 15 make sure you have the line underneath the equality symbol! "at least 15" means it ca also be 15!)

put them together.

2n ≥ 15

hope this helped! :D
