Part a: solve –vp + 30 < 45 for p. show your work. (4 points)
part b: solve 3w – 6r = 30 for r. show your work.

-vp+30<45  subtract 30 from both sides

-vp<15  divide both sides by -v  (remember to reverse inequality sign whenever you multiply/divide by a negative value!)

p>-15/v

...

3w-6r=30  divide both sides by 3

w-2r=10 subtract w from both sides

-2r=10-w  divide both sides by -2

r=(w-10)/2
