Arianna runs up 4 flights of stairs and then runs down 4 flights of stairs. does this situation represent additive inverses? explain.

Yes due to the fact that additive inverse is the oppsite. so she runs up +4 and runs down -4.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
