N-6=2n-n

pls help solve :)

eorder the terms:

-6 + n = 2n + -1n

Combine like terms: 2n + -1n = 1n

-6 + n = 1n

Solving

-6 + n = 1n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-1n' to each side of the equation.

-6 + n + -1n = 1n + -1n

Combine like terms: n + -1n = 0

-6 + 0 = 1n + -1n

-6 = 1n + -1n

Combine like terms: 1n + -1n = 0

-6 = 0

Add '6' to each side of the equation.

-6 + 6 = 0 + 6

Combine like terms: -6 + 6 = 0

0 = 0 + 6

Combine like terms: 0 + 6 = 6

0 = 6

Simplifying

0 = 6

Combine like terms: 0 + -6 = -6

-6 = 6 + -6

Combine like terms: 6 + -6 = 0

-6 = 0

Step-by-step explanation:

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.
