2x-5y=-28 find the value of y when x equals -19
nydimaria [60]
<h3>Question:</h3>

2x-5y=-28 find the value of y when x equals -19

<h3>Answer:</h3>

Y = - 2

<h3>Step-by-step explanation:</h3>

First you plug in -19 where x is 2(-19)-5y = -28

Remove parentheses               -2 · 19-5y= -28

Multiply -2 by 19                       -38-5y= -28

Add 38 to both sides               -5y = 10

Divide both sides by -5            [tex]\frac{-5y}{-5} =\frac{10}{-5}[/tex

you will get -2 which is the answer.


Hope this helped!

What is the speed of a snake that moves 20 m in 5 seconds ?
pogonyaev

The speed of the snake is 8.95 miles per hour.

Step-by-step explanation:

Step 1:

The snake travels at a speed of 20 meters in 5 seconds.

We will need to determine the distance it covered in a single second. To do that we divide the distance covered in 5 seconds by 5.

The distance covered in 1 second = \frac{20}{5} =4.

So the snake is moving at a distance of 4 meters per second.

Step 2:

To convert the speed of the snake from meters per second to miles per hour, we multiply the speed in meters per second by 2.23694.

So to attain 4 meters per second in miles per hour, we multiply it by 2.23694.

4 meters per second = 2.23694(4) = 8.94776 miles per hour.

Rounding this off, we get the speed of the snake as 8.95 miles per hour.
