20-2p > -2(p+2)+4p
20-2p > -2p-4+4p
-4p+2p -4p+2p
20-4p > -4
-20 -20
-4p > -24
divided by -4
p < 6

x + 1 + 1 + 6x > 3 (x - 4) - (x - 4)
7x + 2 > 3x - 12 -x + 4
7x + 2 > 2x - 8
7x - 2x > -8 - 2
5x > -10
x > -2
OpenStudy (anonymous):

-6(1+6x)<6(1-5x)
OpenStudy (texaschic101):
-6(1 + 6x) < 6(1 - 5x)
-6 - 36x < 6 - 30x
-36x + 30x < 6 + 6
-6x < 12 -- divide by -6 and change inequality sign
x < -2
OpenStudy (anonymous):
thanks
OpenStudy (texaschic101):
oops....change the sign
x > -12
OpenStudy (anonymous):
ok

2(1-4r)<-2(r+3)-4
OpenStudy (texaschic101):
2(1 - 4r) < -2(r + 3) - 4
2 - 8r < -2r - 6 - 4
2 - 8r < -2r - 10
-8r + 2r < -10 - 2
-6r < -12
r > 2

thanks
