Answer:

x=28

Step-by-step explanation:

Hey There!

To find the value of x we want to get rid of the 7

To do so we use inverse operations and multiply by 7

whatever you do to the one side you do to the other

7x7 cancels out

7x4=28

we're left with

x=28

hope this helps!

Answer:

28

Step-by-step explanation:

To find x, we have to get x by itself. In this scenario, we have to multiply 7 on both sides. This will result in:

x=28

Equations and inequalities

Can sombody help me about that topic and write me some guided notes about them

Answers

Inequalities and equations use similar steps to solve, but inequalities give a range of numbers that can represent the variable while an equation will give a direct answer.

Example:

4+5x=24

First you would subtract 4 or add the opposite of 4 from 24.

4+5x=24
+(-4) +(-4)
—————
5x=20

Then divide each side by 5 or multiply each side by the reciprocal of 5 to isolate the variable.

1/5*5x=20*1/5 (reciprocal)
X= 4

You would use the same steps in an inequality but end up with a different sign.

Step-by-step explanation:

12 feet would be 144 so you have to add three inches to get 147

another way to solve it would be to divide 147 by 12 to get 12.25 which is equal to 12 ft 3 in

a cylinder has a height of 19 feet. the volume is 3,818.24 cubic feet. what is the radius of the cylinder? use ​π ≈ 3.14

Answers

Answer:

The radius is 32 cubic feet

Step-by-step explanation:

The formula to find the volume of a cylinder is V=Bh or V=πr2h. So you would need to work backwards because you already have the volume and height.

3,818.24= 3.14r2*19

3,818.24= 3.14r*38

Because of the associative property you can multiply 3.14 by 38

which is 119.32

So the next expression would be

3,818.24= 119.32r

How do you reverse multiplication? You need to devide both sides. In this case, you need to divide 3,818.24 by 119.32.

To get 32=r

32sq ft. your equation would be 19 x 3.14r2=3,818.24
