Answer 2

405<x<495

Answer 3

what

Answer 4

I think A bc 405<x<495 would come out 2 be a

Answer 5

this girl told this is the answer
That would mean that you want x≤475 and x≥425 calories!
The only inequality that fits this is A). Since |c - 450| ≤ 45 can be written as:

-45≤c-450≤45
Add 450 to both sides and get 425≤c≤475, which is the same as x≤475 and x≥425 calories =)
