Treat these as if they were equations but keeping the in-equality sign instead of the equal sign,
EXCEPT
when you multiply or divide the in-equation by a negative, you must reverse the inequality sign.
e.g.
last one:
-8x > -64
I would have to divide by -8 to get +x , so
x < 8
1st one:
x + 8 < -28
x < -28 - 8 , I did not multiply/divide so no big deal
x < -36
you do #2, let me know what you get
1. x + 8 <-28
a) x <-36
b) x <-20
c) x <20
d) x <36
2. p/8 > -5
a) p > 40
b) p > 3
c) p > -13
d) p > -40
3. -8x > -64
a) x < 8
b) x > 8
c) x <-72
d) x > 72

yes, but be more confident in your choice
