1. x<-4??? That -x is obnoxios. 2. 10% of 750 is 7.5 then 20% would be 15. 4. Yes 6. True 7. Depends, so thats False 8. Do mulitpliaction first, and then divide -8 by -8 which gets you I think -1. 9. Two negetives = a postive -3+7= -4 10. B 11. ? That one takes to much thinking power. I think you times 16 into 18 I can't recall. 12.(showing work) ^ 3x+12-6x<-9 -3x+12<-9 Minus 12 from each side. -3x<-21 divide both sides by -3. Turn your sign to > when dividing by a negetive.
you get.
x>-7
13.
D=3500
R= 175
So let T=x
3500= 175*x
Divide each side by 175.
Then x would= whatever that is.
Fun!
11) 18 * .06 = 1.08
12) 3(x+4) – 6x < -9 3x+ 12 - 6x < -9 -3x< -21 x > 7
13) 3500 miles = 175 miles/hour * x miles drop out
3500miles/175miles/hour = x
20 hours C
any thing eles dealing with math send it my way i love it
