Given the equation y = x-2, you substitute 5 for x. Check all true statements below.

A) x is temporarily replaced with 5.

B) The equation becomes y = 5-2.

C) y is 3.

D) The equation y = x - 2 is no longer true.

E) The equation y = x – 2 is still true, just with
specific values.

A, B, C

Step-by-step explanation:

I believe those are the answers. A B and C are derived from common sense.

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.
