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

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
