Solve the inequality. Explain all steps and identify the properties used.
3a−4≤5

a≤3

Step-by-step explanation:

3a-4≤5

Move constant to the right hand side and change its sign

3a≤5+4

Add the numbers

3a≤9

Divide both sides of th inequality by 3

a≤3

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.
