You take your car to an auto repair shop. The charge for repairs is $48 per hour plus the cost of parts. If
the car needs new parts that cost $256 and the final bill was $616, then how long did it take to repair the
car?

Answers

Answer 1
It took 7.5 hours to repair the car.
Steps: You subtract 256 from 616: 616 - 256 = 360. Then, you divide 48 from 360 and get 7.5. Hope this helps.
Answer 2

Answer:

7.5 Hours

Step-by-step explanation:

48x + 256 = 616

      - 256 = -256

-----------------------------------

48x =  360 divide both side by 48

-----     -------

48        48

x = 7.5

Can anyone help me with my algebra homework ?

Answers

Answer: No, it is not possible

Why not? Because of the phrasing "share an arm AB". If two angles share a common line, segment or ray, then they are considered adjacent angles by definition. You can think of two rooms sharing the same wall. Those rooms are adjacent. So we cannot have nonadjacent angles sharing the same arm AB.

Answer:

37

Step-by-step explanation:

180-(81+62)=37

Answer:

x = 37°

Step-by-step explanation:

The sum of all internal angles in a triangle will always equal 180.

Thus, we know that 81 + 62 + x must equal 180.

81 + 62 + x = 180

143 + x = 180

Subtract 143 from both sides:

x = 180 - 143

x = 37

Answer: x = 37°

CDs cost $5.96 more than DVDs at all bets are off electronics. How much would 6 CDs and 2 DVDs cost if 5 CDs and two DVDs cost $127.73

Answers

Cd= x =5,96
Dvd=y

5x+2y=127,73
2y = 127,73 - 5 (5.96)
2y = 127,73 - 29.8
2y = 97.93
y = 97.93/2 = 48.965

x=5,96
y=48.965

6x+2y = 6(5,96) + 2(48.965) = 35.76 + 97.93 = 103.89

Final answer: 103.89

Amtrail trains provide efficient, nonstop transportation between Los Angeles and San Diego. Train A leaves Los Angeles headed toward San Diego at the same time that Train B leaves San Diego headed for Los Angeles, traveling on parallel tracks. Train A travels at a constant speed of 84 miles per hour. Train B travels at a constant speed of 92 miles per hour. The two stations are 132 miles apart. How long after they leave their respective stations do the trains meet

Answers

Answer:

0.75 hour or 45 mins

Step-by-step explanation:

From the question, we are told that:

Speed of Train A = 84 miles per hour. Speed of Train B = 92 miles per hour.

Total speed travelled by both trains =

84mph + 92mph

= 176 mph

The distance between the two stations = 132 miles.

We are asked in the question to: find out how long after they leave their respective stations do the trains meet.

This means we should calculate the time

Time = Distance/ Speed

= 132 miles/176 miles per hour

= 0.75 hour

We can convert to minutes if we like

1 hour = 60 minutes

0.75 hour =

0.75 hour × 60 minutes/ 1 hour

= 45 minutes

Therefore, the trains meet after 0.75 hour or 45 minutes after they have left their respective stations.

Find the slope, if it exists, of the line containing
(-8,-5) and (-19,- 13)

Answers

Answer: 8/11

Step-by-step explanation:

To find slope you can use this formula:

y2-y1/x2-x1

substitute the values with the ones from the 2 points

-13-(-5)= -8

-19-(-8)=-11

you then divide -8/-11

and you get 8/11

8/11 is the slope of those 2 points.
