I an fairly sure that I did the solving right but im not sure if I flipped the signs correctly. If anyone would briefly look over some of these and tell me if I have the inequality signs the right way I will greatly appreciate it.

1) -12> 24x
-1/2> x


2) -7k< 63
k> -9

3)8a -15 > 73
a> 11

4) 57 -4t > 13
t<11

5) -18 -5y > 52
y<-14

6) 14 -4y > 38
y < -6

7) 4(x+3) < 44
x< 8

8) 2 (m-3) +7 < 21
m<10

9) 4(n-2) -6 > 18
n>8

10) 9x+18>9x -27
x> -2.5

11) 6x -13 < 6(x-2)
x< 1/12

12) -12x+60+12x< 180
x= any real numbers

13) -21x+49 +21x>50
Not possible

Why don't power company places apparent power meter instead of watt meter at customers' sites ?It is easy that the power company can charges its customer penalty for poor power factor.

I need help finding the speed of an object if I was given the distance covered (160 km) and the average speed of the object (67.0 km/h). The objects speed during the first half of the distance is 88.0 km/h. Could anyone please explain how to find the speed of the second half of the distance?

Thanks. =)

I can't bear to be around a spider, the sight of a large one makes me ill. Other animals don't bother me though (like snakes, mice, etc)

I'm not really talking about carnivores, like man-eating tigers.
