What is the value of x?
ella [17]

Answer:

x=70

Step-by-step explanation:

The same side interior angles add to 180 degrees when m and n are parallel

45+ 2x-5 = 180

Combine like terms

40+2x = 180

Subtract 40 from each side

40-40+2x= 180-40

2x= 140

2x/2 =140/2

x =70

The cost of labor for servicing cars at B&amp;B Automotive is $50 for each whole hour or for any fraction of an hour. There is a
Masja [62]

Answer:

<h2>d. $250</h2>

Step-by-step explanation:

We can use the equation of a straight line to model the cost of servicing the car.

let the cost be y and the number of hours be x

and the charge per hour is m

y=mx+c

y=50x+25

given that the time is 3.45 hours it is assumed that the charge is for 4 hours since for a fraction of 0.45 hours we are charged $50

y=50(4)+25

y=200+25

y=$225
