Mathematics

|6x + 5| = 7 · 3

|6x + 5| = 21

6x + 5 = 21 (1st equation)

-6x + 5 = 21

(1st equation)

6x = 21 - 5

6x = 16

x = 8/3

(2nd equation)

-6x - 5 = 21

-6x = 21 + 5

-6x = 26

x = -13/3

so all of the solutions are;

x = -13/3, 8/3

e-lub [12.9K]

The distance between the two cars is now 320 yards.

<h3 /><h3><u>Distances</u></h3>

To determine what is the distance between the two cars now if they did not collide the following calculation must be performed:

  • 500 - (500 - 405) - (500 - 415) = X
  • 500 - 95 - 85 = X
  • 500 - 180 = X
  • 320 = X

Therefore, the distance between the two cars is now 320 yards.

I work at a hotel and my time is 5:30 am to9:30am. I have to put out the breakfast for 6:30 and break down at 9:30 am. How many
erik [133]
So, with 12 check outs and 4 stays over you will have to clean up 16 rooms ( I assume that the hotel has the habit of cleaning up the room even if people stay overnight)

so the time between 9 am and 3 pm is 4 hours, that is 4*60=240 minutes.

This means it's 240/16=120/8=60/40=15, 15 minutes per room.

About the first part of the sentence: I assume that you can start washing the dishes alrady at 6:30 (dishes you used for preparation,etc) - so you can clean up from 6:30 till 9:30 - that is three hours!
