Using distributive property you would do what it is in the parentheses first. So -5(3x-4) would be -15x+20. It would be a positive 20 because you multiplied a negative with another negative. Youre equation now would be -15x+20+4=114.
Using like terms you would simplify 20 and 4 to get -15x+24=114. To get variable x alone you would subtract 24 to both sides of the equal sign to get -15x=90. Now you would just divide -15 to both sides to get x alone. So you would now get x=(-)18.2

-15x divided by 90 is 6, not 18.2. So your answer is -6

andreyandreev [35.5K]

Answer:

<u>Cost = 25 + 50h</u>

cost for 8 hours of work = $425

cost for 10 hours of work = $525

Step-by-step explanation:

The question is as following:

A plumber charges $25 for a service call plus $50 per hour of service write an equation to represent the cost of hiring this plumber​.

what will be the cost for 8 hours of work? 10 hours of work?​

=======================================================

A plumber charges $25 for a service call plus $50 per hour

<u>Cost = 25 + 50h</u>

Where h is the number of hours of service

8 hours of work: h = 8

Substitute with h = 8 at the equation of cost

<u>Cost = 25 + 50* 8 = $425</u>

10 hours of work: h = 10

Substitute with h = 10 at the equation of cost

<u>Cost = 25 + 50 * 10  = $525</u>
