Solve for L. P = 2L + 2w

L = 2/P - W

Step-by-step explanation:

I'm going to assume you were asked to just isolate for L without any other given numbers because I've needed to do that in math class before.

First, subtract 2W from both sides.

P - 2W = 2L

Now divide both sides by 2.

L = 2/P - W

I hope this helps you somewhat.

There are 375 star stickers and 125 heart stickers.

There are 500 stickers with 20 stickers per sheet; 500/20 = 25 sheets of stickers.

25% of each sheet is hearts; 25/100(20) = 5 heart stickers per sheet.  5(25) = 125 total heart stickers.

20 stickers per sheet - 5 heart stickers per sheet = 15 star stickers per sheet.  15(25) = 375 total star stickers.
