2 > 8-3x > 1/2
2 > 8-3x and 8-3x > 1/2
3x > 8-2 and 8-1/2 > 3x
3x > 6 and 15/2 > 3x
x > 2 and 7.5/3 > x
x > 2 and 2.5 > x
So,
2 < x < 2.5
In interval notation: (2; 2.5)
Easy eh? 10 points please!

(x+5)(x-5)<=0 x+5=0 x=-5 x-5=0 x=5 you create a signum table x -5 5 x+5 - - - - 0 ++++++ x-5 - - - - - - - - - - - - - 0 +++++ (x+5)(x-5) + + +0 - - - -0 +++ the inequality would desire to be much less or equivalent to 0 so which you will pick the parte of the table the place the inequality is adverse , So x is between -5;5

4>16-6x>1 (get rid of fraction)
-12>-6x>-15 (subtract 16)
2
(2, 15/6)
Interval notation like you requested.

2 > 8 - 3x > (1/2)
-6 > -3x > (1/2) - 8
-6 > -3x > (1/2) - (16/2)
-6 > -3x > (-15/2)
2 > x > 2.5
(2,2.5)
