Given: 3x < 9. choose the solution set. {x | x < 3} {x | x > 3} {x | x < 27} {x | x > 27}

3x<9

x = 9/3 = 3

answer is {x | x < 3}

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.

i believe it is the square root of 122 because when you turn it on it's side, to where the 5 inches is on the bottom, it looks like it is the same length.
