Solve −np − 90 < 30
for n
. Show your work.
Also solve 5m − 3h = 45
for h
. Show your work.
-np - 90 < 30 subtract 30 from both sides, add np to both sides
-120 < np divide both sides by p
-120 / p < n
9m - 3h = 45 add 3h to both sides, subtract 45 from both sides
9m - 45 = 3h divide every term by 3
3m - 15 = h
Corrected answer....thanks to guest for spotting my error !!!
