Answer: x = 9.5
Step-by-step explanation:
3x - 12 = 5x - 31
First, add 31 to each side.
We get:
3x + 19 = 5x
Subtract 3x from each side.
We get:
19 = 2x
Divide both side by 2
9.5 = x

Answer:
v = 0.416 m/s
Step-by-step explanation:
Give that,
Distance covered by a train, d = 50 m
Time taken, t = 120 s
We need to find the speed of a train. The formula for speed of an object is equal to the total distance covered divided by total time taken. It can be given by :

So, the speed of a train is 0.416 m/s.
Answer:
y = 2x + 6 and 2y-4x=12 are the same line, so have infinitely many solutions.
Step-by-step explanation:
2y - 4x = 12
This is the same as y = 2x + 6
