Solve for y in the equation and give the reason for each step in the process

y=5

Step-by-step explanation:

: given

   : distributive property (multiply things in parentheses by the outer value of 3)

        : add 4 to both sides to isolate the right side y value

                : subtract 3y from both sides to further isolate "y" and the constant

                   : divide by 2 on both sides to get value for a single "y"

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.
