I want to make sure that I am on the right track with these inequalities. I cannot figure how to type the mathmatical symbols in the text, so I've typed words instead in some cases. Thanks for the help!

1) The set notation for the inequality: 1/4y - 1/3 < y + 2 = ? ( I've come up with {y|y > -28/9} is this right?

2) The set notation for the inequality: 3 is less than or equal to 4 + 3x/2 is less than or equal to 2. Is the answer 0??

3) 4 < -z -4 < 11; I come up with: {z|-8 > z >-15} Is this right?
