Write an equation for each situation and solve. define your variable and make sure your solutions have units. a computer repair bill was $180. this included $45 for parts and $45 for each hour of labor. find the number of hours of labor. !

33 3/4 hours or 33 hours and 45 minutes

Step-by-step explanation:

Let h=hours

180=45+45h

Solving for h...

135=45h

h=33.75 or 33 hours and 45 minutes

45 + 45x = 180

subtract 45 from both sides :

45x = 135

divide by 45 to get x by itself :

x = 3

Your answers are :

45 + 45x = 180

and

x = 3

d 600 because 15*10*2=300

300+300=600
