Answer:

x = 5

Step-by-step explanation:

6x - 3 = 3x + 12

-3x -3x

_____________

3x - 3 = 12

+3 +3

_____________

3x = 15

15 divided by 3 = 5

x = 5

You can double check this by replacing x with (5)

If it is right both sides should equal the same

6(5) - 3 = 3(5) + 12

30 - 3 = 15 + 12

27 = 27

This would prove that x = 5

Answer:

The value of x is $\frac{-2}{5}$ .

Step-by-step explanation:

Given expression is:

$\frac{2}{3}(x-2)=4x$

We have to solve this for x.

First we will multiply both sides of the equation by 3

$3*\frac{2}{3}(x-2)=4x*3$

2(x-2) = 12x

2x-4=12x

Now we will be subtracting 2x from both sides of the equation

2x-2x-4=12x-2x

-4=10x

10x=-4

Dividing both sides by 10

$\frac{10x}{10}=\frac{-4}{10}\\\\x=\frac{-2}{5}$

Hence,

The value of x is $\frac{-2}{5}$ .

In the figure to the right, if AC=19 and BC=16, what is the radius? *For a circle*

ch4aika [34]

Answer:

The radius of the circle is 10.2 units

Step-by-step explanation:

The complete question is

In the figure to the right, if AC=19 and BC=16, what is the radius?

A circle has center A. Points B and D are on the circle, with B on the left and D near the bottom. Point C lies outside the circle such that the line segment A C passes through point D and the line segments A B and B C form a right angle.

The radius is approximately (Round to the nearest tenth as needed.)

The picture of the question in the attached figure

we know that

In the right triangle ABC

Applying the Pythagorean Theorem

$AC^2=AB^2+BC^2$

substitute the given values

$19^2=AB^2+16^2$

solve for AB

$AB^2=19^2-16^2$

$AB^2=105\\AB=10.2\ units$

Remember that the radius is the same that the segment AB

therefore

The radius of the circle is 10.2 units

Simplify 6(x + 4). 10x 6x + 4 6x + 24

Dominik [7]

Answer:

6x + 24

Step-by-step explanation:

Using the distributive property (the distributive property of multiplication is a(b + c) = a * b + a * c), we get:

6(x + 4)

= 6 * x + 6 * 4

= 6x + 24
