Dahasolnce [82]

Answer:

5 hours

Step-by-step explanation:

1. Find out how many dollars he earned on Saturday

3 x 6 = 18

He earned 18 dollars on Saturday.

2. Subtract 18 from 48 since that is from Saturday, not Sunday

48 - 18 = 30

3. Divide 30 by 6 to see how many hours he worked on Sunday

30/6 = 5

A person on a moving sidewalk travels 40 feet in 8 seconds. The moving sidewalk has a length of 200 feet. How long will it take
beks73 [17]

Answer:

The man covers 200 ft in 40 seconds.

Step-by-step explanation:

A person is moving on the sidewalk from one end to the other end.

He walks 40 feet in 8 seconds.

Therefore his speed = \frac{distance covered}{time}

                                   = \frac{40}{8}

                                   = 5 ft/s^{2}

He covers the sidewalk distance at a rate of 5 feet every second.

To calculate the time taken to cover 200 ft,

time = \frac{distance to be covered}{speed}

time =\frac{200}{5}

<u>time  = 40 seconds</u>

Hence the man covers 200 ft in 40 seconds.

-3x-y=-17 4x + 2 y equals 20
ExtremeBDS [4]
-3x - y = -17
4x + 2y = 20

multiply one part of the equation so that we can be able to use the process of elimination.

(-3x - y = -17)2
4x + 2y = 20

Now we have:

-6x -2y = - 34
4x+2y= 20
------------------------
-2x = -14

Divide -2 on both sides.

-2x = -14
/-2       /-2

x = -7.


=============================================

To solve for y, we just have to substitute the value of x to any of the equation given above, that we feel comfortable with. And I'm going to choose this equation: 4x + 2y = 20


4x + 2y = 20

4(-7) + 2y = 20

-28 + 2y = 20

Add 28 on both sides

-28 + 2y = 20
+28          +28
---------------------
2y = 48
/2      /2

y = 24.


The last thing you would do is to check if the answers is correct.
All you have to do is plug in the values of x and y into both equations and see if they equal to one another.

You may have to do this by yourself :P

Anyways, if you have any questions about this topic, feel free to PM me or any other users interested. Thank you for being part of Brainly! Have a nice day!
