Answer:

x=-5

Step-by-step explanation:

Set " 4x+20" equal to 0 (4x+20=0)

Do the opposite operation of 20 (in this case is subtraction) and subtract 20 from both sides (4x+20-20=0-20).

You'll be left with 4x=-20.

Divide both sides by 4 (4x/4=-20/4).

4 divided 4 equals x.

-20 divided by 4 equals -5.

x=-5.

What is the volume of the cylinder with a radius of 8 and height of 4<br><br>

mr Goodwill [35]

Answer:

Hey there!

The formula for cylinder volume is $r^2h\pi$ , where r is the radius, h is the height, and $\pi$ is a constant, roughly equal to 3.14.

Substituting all of these values into the equation:

$8^2(4)(3.14)$

$804.84\\$

Thus, the volume for the cylinder is 804.84 units cubed.

You weigh a gallon of liquid in science class and learn that it is approximately 7.7 pounds. You pass the liquid to the next gro

IceJOKER [234]

Answer:

7.7 pounds = 3.5 kilograms

Step-by-step explanation:

Given that,

Weight of a gallon of liquid = 7.7 pounds

We need to find weight in kilograms.

We must know the relation between pounds and kilograms and it is as follows :

1 kilogram = 2.20 pounds

1 pounds = (1/2.2) kilograms

7.7 pounds = (7.7/2.2) kilograms

= 3.5 kilograms

Hence, 7.7 pounds is equal to 3.5 kilograms.
