Best ResponseYou've already chosen the best response.1A: np90<30 add 90 to both sides to get np alone: np<120 then divide by p: n<120/p then multiply both sides by 1 (so you can get n not n): n>120/p note that the less than sign changed direction. When ever you change the sign of both sides the inequality changes direction. This is just a rule. B:5m3h=45 move 5m with addition: 3h=45+3m then divide by 3: h = (45+3m)/3
