Answer:
m >9 or m < -9
Step-by-step explanation:
-2|3m|+3<-51
Subtract 3 from each side
-2|3m|+3-3<-51-3
-2|3m|<-54
Divide each side by -2, remembering to flip the inequality
-2|3m|/ -2>-54/-2
|3m|> 27
To get rid of the absolute values, we separate into two inequalities, one as written and one negative, remembering to flip the inequality
3m >27 or 3m <-27
Divide by 3 on each side
3m/3 >27/3 or 3m/3 <-27/3
m >9 or m < -9
The answer would be y=4x-18.

Let x = hours to meet
train one has a 2 hour head start or 210 km head start
210 + 105x = 135x
30x = 210
x = 7 hours to meet
Answer:
Step-by-step explanation:
Both expression are the same :
14 = 2(x + 3)
By expansion :
14 = 2*x + 2*3
14 = 2x + 6
Hence ;
Both expression are the same
Weight of one circle :
Final weight on both sides are equal:
Weight on Left hand side = 14
Weight on right hand side = 3*x + 3*x
Weight on Left hand side = Weight on right hand side
14 = 3x + 3x
14 = 6x
x = 14 / 6
x = 2.333
