 What's an altitude?!
A guy named Bob wants a bagel. He has 20 dollars and wants to buy as many bagels as possible. Shop A will give you 20 bagels for 5 bucks and 1 bagel for 50¢. Shop A will also give you 2 bagels for 75¢, 10 bagels for 2 bucks, and 100 bagels for 30 bucks. Shop B will give you 5 bagels for a dollar, 25 bagels for 4.50 dollars, 60 bages for 10 dollars and 3 bagels for 75¢. If Bob wants to get as many bagels as possible, how much money does he have?
Read carefully :3

 proofs are required in almost all geometry questions... like you can't say two angles are equal simply by eyeballing the figure because they're never to scale, so you have to provide a reason... idk man i live in australia so it may vary in the us ; ^ ;
solve for x (3x1)/2  (2x+1)/3 = 5
