Answer:
The correct answer is: C
Step-by-step explanation:
2(4x - 5) < 14x + 8
First multiply 2 by 4x and -5
8x - 10 < 14x + 8
Now find out what x is
Move 14x to the left
8x - 14x - 10 = 8
Then move 10 to the right and change it's sign to plus
8x - 14x = 8 + 10
Now combine like terms
-6x = 18
Now divide 18 by 6 to get x
x = 18/-6
x = -3
Yes it will. For every one hour, the train travels 170 miles. That’s the rate of change/ the ratio-> 1:170
