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

Part A: subtract 30 from both sides to get -vp<45. Then divide both sides by -v and flip the signs to get p>45/-v

Part B: subtract 3w from both sides to get -6r=30. Then divide -6 by both sides to get 3w/-6-5=r

Here are the answers to the ones that i could see.

You must find the surface of the block therefore 98187 dived by 5628 = 583m squared
