X= 240/7

So we know that according to the law of multiplying exponents that when multiplying them, you are just adding them together

With that in mind, x/6+x/8=10

From here, we can just solve for x!

Multiply both sides by 24

4x+3x=240

Add the x’s

7x=240

Anddddd divide both sides by 7

x=240/7

Remember, you can always double check your answer by plugging in your answer into your original equation! :)

Use substitution to solve the following system of equations. -2x + 4y = -18 AND x = y + 3

loris [4]

Answer:

x = -3 ; y = -6

Step-by-step explanation:

x = y + 3

-2x + 4y = -18

-2(y+3) + 4y = -18

-2y -6 + 4y = -18

2y = -12

y = -6

x = -6+3

x = -3

Find the value of x. 5 X 11 y

katrin [286]

The value of the variable is 4√5. Then the correct option is C.

<h3>What is the triangle?</h3>

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

The similar triangles are shown in the diagram.

16 / x = x / 5

x² = 16 × 5

x = 4 √5

Then the value of the variable is 4√5.

Then the correct option is C.

The volume, V, of a cylinder is V= \pi^2h, where r is the radius of the cylinder and h is the height. Using rounding to the near

mylen [45]

To solve this problem you must apply the proccedure shown below:

You have that the radius of the cylinder is 2.75 inches and the height is 5.21 inches. Therefore, you only need to substitute these values into the formula for calculate the volume of a cylinder:

$V=\pi r^{2}h\\V=\pi(2.75in)^{2}(5.21in)\\V=123.78in^{3}=124in^{3}$

Therefore, as you can see, the answer is: The volume of the cylinder is 124 in³.
