Answer: B
Step-by-step explanation: if you divide 27/30 by 3 you get 9/10
You have to move variables on one side and constants on the other
aby - b + b = c + b
aby = c + b
y = (c + b)/ab
Let y be the unknown number
The other number is x - 12
I'm pretty sure it is 1 out of nine or 1 out of 8.
1). 2x-1>0
2x>1
x>½
2) 21-3y<0
-3y<-21
y>7
3) 5-3c>80
-3c>75
c<-25
