the chapters were easy, and so were the quizes. now i'm on the test and i can't get any of them. helppp? :]

Answer 1

1.) 0
2.)450-x<180
3.)150+6x<8x
150<2x
75 4.)2(x-5)<2x-17
2x-10<2x-17
2x<2x+7
0<7
5.)-4 -10 -10

i hope it helps

Answer 2

The first question is not at all clear, are you looking for 20.103 > 19.868?

$M < $450 - $180

$150 + $6s < $8s

2(x-5) < 2x -17
2x -10 < 2x - 17
-10 < -17
This is obviously false, no value of x will make it true.

-4 < t + 6 < 10
10 < t < 4

Answer 3

i dont think we should give you the answers to your test...thats cheating...srry =}
