Solve the equation. –x 8 3x = x – 6 x = –18 x = –14 x = 2 x = 4

LenKa [72]

The value of the variable x in the equation –x + 8 + 3x = x – 6 is - 14.

<h3>How to find variable in an equation?</h3>

The variables of an equation can be found as follows:

–x + 8 + 3x = x – 6

The variable in the equation is x.

Therefore,

–x + 8 + 3x = x – 6

combine like terms on the left side

-x + 3x + 8 = x - 6

2x + 8 = x - 6

subtract x form both sides of the equation

2x - x + 8 = - 6

x + 8 = -6

subtract 8 from both sides

x = -6 - 8

x = - 14

Problem A park has a large circle painted in the middle of the playground area. The circle is divided into 444 equal sections, a

Vladimir79 [104]

Answer:

25 $\pi\ m^2$

Step-by-step explanation:

Given that:

A large circle in the park has its middle part painted.

The circle is divided in 4 equal parts.

Radius of the circle = 10 meters

To find:

Area of each section of the circle, $A$ = ?

Solution:

Here, we need to find the area of the bigger circle first and then need to divide it into 4 equal parts to find out the answer.

First of all, let us have a look at the formula for area of a circle with given radius $r$ :

$Area = \pi r^2$

Here, $r = 10 m$

Putting the value in the above formula, we get:

So, area = $\pi 10^2 = 100\pi\ m^2$

Now, there are 4 equal parts of the circle, therefore area of each section will be equal.

Area of each section of the circle:

$\dfrac{100\pi}{4} = \bold{25 \pi}\ m^2$
