Question

in a chemical process, between 77g and 85g of carbon is added to a mixture. let C be the amount of carbon. write an absolute value inequality describing the amount of carbon added.

Answer 1

alright so you know your bounds are 77 and 85 and they want you to set up an inequality for |x|.. this means that

\[|x|>77\]
and

\[|x|<85\]

you can write these as one inequality by putting it in the middle of hte two

\[77<|x|<85\]

Answer 2

Thank You!!!! :)
