move < to left
2*|x|-x<3
split into possible cases
2x-x<3, x<0
2*(-x)-x<3, x<0
solve inequalities
[0,3]
[-1,0]

Answer:
okay he's saying that each student gets 25 points to start with and then they get five more like 25 / 25 * 5 or like 25 + 5 or 25 - 5 like represent those numbers and like get the number or something like that
since we know the plumber charges $32 for one hour of work, if the plumber works
1 hour, that's 32(1)
2 hours........ 32(2)
3 hours.........32(3)
4hours...........32(4)
x hours...........32(x) => 32x.
the cost of materials is $46, so your total charge for getting the lizard out of the bathtub pipe is the hours rate plus the 46 bucks, namely 32x + 46, and incidentally we know that's $134.
![\bf 32x+46=134\implies 32x=88\implies x=\cfrac{88}{32}\implies x=\cfrac{11}{4} \\[2em] x=2\frac{3}{4}\impliedby \textit{2 hours and 45 minutes}](https://tex.z-dn.net/?f=%20%5Cbf%2032x%2B46%3D134%5Cimplies%2032x%3D88%5Cimplies%20x%3D%5Ccfrac%7B88%7D%7B32%7D%5Cimplies%20x%3D%5Ccfrac%7B11%7D%7B4%7D%20%5C%5C%5B2em%5D%20x%3D2%5Cfrac%7B3%7D%7B4%7D%5Cimpliedby%20%5Ctextit%7B2%20hours%20and%2045%20minutes%7D%20)
