Aplumber charges a $45 fee to make a house call and then $25 for each hour of labor. the plumber uses an equation in the form es027-1.jpg to determine the amount to charge each customer. what is the value of m in the equation?

Value of m is 25.

Step-by-step explanation:

Given:

Permanent charge of Plumber = $ 45

Amount per hour of labor = $ 25

Plumber uses the Equation,

Total Amount, y = mx + c

To find: Value of m in the equation.

Let x be the number of hour of labor of the Plumber.

Then cost of labor = 25 × x = 25x

⇒ Total Amount of Plumber = 25x + 45

So, y = 25x + 45

So comparing with given equation,

m = 25

Therefore, Value of m is 25.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
