-2 (-3x+1) = -2x - 6 (-2x - 3)

x= -5

Step-by-step explanation:

First you multiply:

-2(-3x)-2(1) = -2x -6(-2x) -6(-3)

Then combine like terms:

6x -2 = -2x +12x +18

Then Subtract 6x from both sides:

6x -2 -6x = 10x +18 -6x

-2 = 4x + 18

Subtract 18 from both sides:

-2 -18 = 4x +18 -18

-20 = 4x

Divide 4 from both sides to get:

-5=x

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
