Please help!!

Graph the inequalities.

7. George weighs 212 pounds. If he is currently losing 4 pounds a week, how many weeks does he need to diet and exercise so that he weighs no more than 180 pounds?

Answer 1

do 212-4 until you get to the number 180. Once you get to 180, count how many times you minused 4. since 4 pounds is equal to 1 week, how ever many times you minused, will change to weeks.

sorry if this doesn't make sense, but basically if you do 213-4 3 times until you get to 180, then the answer will be 3 weeks.

btw I don't think the answer is 3.
