What is equation?Equation, also known as a statement of equivalence between two expressions with variable- and/or number-based components. In essence, equations are questions, and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics.
An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated by the symbol "equal."

3/x-1-4x-1/x+1 =x^2+5/x^2-1-5
After thoroughly calculating the equation, we conclude that x⁴ + 4x³ - 6x² - 2x + 25 is the simplified form of 3/x - 1 - 4x - 1/x + 1 = x² +(5/x)²- 1 - 5
What is a simplified form?When the top and bottom of a fraction are the same size and still whole numbers, the fraction is said to be in its simplest form or simplified form.
Using 2/4 as an example, 1/2 can be written.
Simplify a fraction by multiplying its top and bottom by the biggest number that will divide them both exactly (they must stay whole numbers). the outcome will be what we call the simplified form.
We have been asked to simply the equation
3/x - 1 - 4x - 1/x + 1 = x² +(5/x)²- 1 - 5
⇒ 3/x - 4x - 1/x + 6 = x² +(5/x)²
⇒ 2/x - 4x + 6 = x² +(5/x)²
⇒ 2/x - 4x²/x + 6x/x = x² +(5/x)²
⇒ (2 - 4x² + 6x)/x = x² +(5/x)²
Multiplying x to both side
⇒ 2 - 4x² + 6x = x² +(5/x)² × x
⇒ 2 - 4x² + 6x = x³ + 25/x
⇒ x³ + 4x² - 2 = 6x - 25/x
⇒ x³ + 4x² - 2 = 6x²/x - 25/x
⇒ x³ + 4x² - 2 = (6x²- 25)/x
Multiplying x to both side
⇒ (x³ + 4x² - 2) x = 6x²- 25
⇒ x⁴ + 4x³ - 2x = 6x²- 25
⇒ x⁴ + 4x³ - 6x² - 2x + 25

What is meant by angles?An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. It is referred to as dihedral angles. The angle formed by the rays lying perpendicular to the two crossing curves at the point of junction is another property of intersecting curves.Angle can also refer to the length of a rotation or an angle. This metric represents the relationship between a circular arc's length and radius.The arc is centered at the vertex and defined by the sides in the case of a geometric angle. When there is a rotation, the arc is defined by any other point and the rotation's image, and it is centered at the rotation's center.10. In the given figure,

(3x - 29)° + (8y + 17)° = 180° [Because they are linear pairs]
⇒ 3x -29 + 8y + 17 = 180
⇒ 3x + 8y - 12 = 180
⇒ 3x + 8y = 192 ............ (1)
Now,
8y + 17 = 6x -7 [Alternate interior angles]
⇒ 6x - 8y = 24 ..............(2)
On adding (1) and (2),
(3x + 8y) + (6x - 8y) = 192 + 24
simplifying the above equation, we get
⇒9x = 216
⇒ x = 216/9 = 24
⇒ x = 24
Now, 6x - 8y = 24
⇒ 8y = 6(24) - 24
⇒ y = (144 - 24)/8
⇒ y = 120/8 = 15
So, x = 24 and y = 15

⇒ 11y - 1 = 3 x 18
⇒ 11y = 54 + 1
⇒ 11y = 55
⇒ y = 5
Therefore, the value of x = 18 and y = 5

7y - 20 + 5x - 38 + 90° = 180° [Angle sum property of a triangle]
⇒ 7y - 20 + 85 - 38 + 90 = 180
⇒ 7y + 117 = 180
simplifying the above equation, we get
⇒ 7y = 180 - 117
⇒ 7y = 63

The saved amount after selling the tank and by using the code is $21.24.
What is selling price?
The selling price is the amount in the form of extra charges which was decided by the shopkeepers for the different commodities. The cost spent by the shopkeeper for the purchase is the cost price. And for profit selling price should be more than the cost price.
According to the question, the given parameter is as written below:
The selling price of the Jellyfish tank is: $24.99
And the discount with special code is: 15 percent
The calculated money saved by using the special code is:
Discount Amount = (24.99 x 15)/100 = 3.7485
Saved money = $24.99 - $ 3.7485 = $ 21.2415 ≅ $ 21.24

how do you solve this
Answer:
45
Step-by-step explanation:
In this picture we can see that they gave us 2 angles.
Angle V has an angle of x+83
Angle S has an angle of 4x - 53
As one of the circle thermoses in mathematics said when there is an angle in the center of the circle, the angle at the circumference is half the angle at the center, which means we could create and equation such that:
angle of angle V = 2 times the angle of angle S
x + 83 = 2(4x - 53)
x + 83 = 8x - 106
189 = 7x
27 = x
Since we know x = 27, we can substitute into the equation angle of S to find what is the angle of TSU:
4x - 53
= 4(27) - 53
= 108 - 53
= 45
Answer:
<TSU = 55°
Step-by-step explanation:
We know that,
Angle at the circumference of a circle is twice the angle at the centre.
Therefore,
2 × <UST = <UVT
Given that,
< UVT = x + 83
< TSU = 4x - 53
Accordingly, we can make an expression like this.
[tex] \sf2 × <UST = <UVT[/tex]
[tex] \sf2(4x - 53) = x + 83 \\ [/tex]
And now solve the above expression and find the value of x.
Let us solve it now.
[tex] \sf8x - 106 = x + 83 \\ \sf8x - x = 106 + 83 \\ \sf7x = 189 \\ \sf \: x = 27[/tex]
And now, according to the question they've asked us to find the value of <TSU.
As we mentioned earlier, they've given that, <TSU = 4x - 53.
So, to find the value of Angle TSU, we have to replace x with 27 and find the value of angle TSU.
Let us solve it now
[tex] \sf \: <TSU = 4x - 53 \\ \sf \: <TSU = 4 \times 27 - 53 \\ \sf \: <TSU = 108 - 53 \\ \sf \: <TSU = 55 \degree[/tex]

Exterior angle, theorem, and triangle sum theorem
Answer:
x = 4
The two interior angles are
14x + 6 = 14 x 4 + 6 = 62°
16x + 4 = 16 x 4 + 4 = 68°
Step-by-step explanation:
The exterior angle of a triangle is the sum of the interior angles:
Here the exterior angle is 130° and the interior angles are
16x + 4 and 14x + 6
So 16x + 4 + 14x + 6 = 130
Gathering like terms and simplifying:
16x + 14x + 4 + 6 = 130
30x + 10 = 130
30x = 120 (subtract 10 from both sides)
x = 4
The two interior angles are
14x + 6 = 14 x 4 + 6 = 62°
16x + 4 = 16 x 4 + 4 = 68°

If an experiment with a random outcome is repeated a large number of times, the empirical probability of an event is likely to be close to the true probability. This mathematical theorem is called The Law of Large Numbers.
The Law of Large Numbers states that on the off chance that a test with an irregular result is repeated a huge number of times, the empirical probability of an event is likely to be near the true probability. The bigger the number of redundancies, the closer together these probabilities are likely to be.The law of large numbers does not ensure that a given test, particularly a little test, will reflect the genuine population characteristics or that a test that does not reflect the genuine population will be adjusted by a subsequent sample.
