Part a: solve −np − 90 < 30 for n. show your work. (4 points) part b: solve 5m − 3h = 45 for h. show your work. (6 points)

Hello there!

Part A: Solve for n; -n*p - 90 < 30
Add 90 to both sides.
-n*p < 120
Divide both sides by p.
-n < 120/p
Divide both sides by -1.
n  120/-p is your answer for part A.

Part B: Solve for h; 5m - 3h = 45
Subtract 5m from both sides.
-3h = -5m + 45
Divide both sides by -3.
h = (-5m + 45)/-3 is your answer for part B.

I hope this helps!

It would be the second one because it passes the vertical line test

Understanding what? lol
