Answer:

X=10

Step-by-step explanation:

Step 1: Subtract 100 from both sides of the equation.

Step 2: Simplify.

Step 3: Subtract 25x from both sides of the equation.

Step 4: Simplify.

Step 5: Divide both sides of the equation by the same term.

Step 6: Simplify.

X=10 :)

Answer:

Step-by-step explanation:

In this question we are given an equation that is 22x + 100 = 25x + 70. And we are asked to find the value of x .

Solution : -

[tex] \longmapsto \:22x + 100 = 25x + 70 [/tex]

Step 1 : Subtracting 100 from both sides :

[tex] \longmapsto \:22x + \cancel{100} - \cancel{100} = 25x + 70 - 100[/tex]

On further calculations we get :

[tex] \longmapsto \: 22x = 25x - 30[/tex]

Step 2 : Subtracting 25x from both sides :

[tex] \longmapsto \:22x - 25x = \cancel{ 25x} - \cancel{25x }- 30[/tex]

On further calculations we get :

[tex] \longmapsto \: \cancel{- }3x = \cancel{ - }30[/tex]

Step 3 : Dividing with 3 on both sides :

[tex] \longmapsto \: \frac{ \cancel{3}x}{ \cancel{3}} = \cancel{\frac{30}{3} }[/tex]

On further calculations we get :

[tex] \longmapsto \: \purple{\boxed{ \frak{x = 10}}}[/tex]

Verifying : -

We're verifying our answer by substituting value of x in given equation . So ,

Therefore, our value for x is correct .

Polynomials are expressions. The solution of the division can be written as [tex]4x^2-27x+167-\dfrac{996}{x+6}[/tex].

Polynomial is an expression that consists of indeterminates(variable) and coefficient, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.

The division of the polynomial  (4x³-3x²+5x+6) when divided by (x+6), can be done in the following manner,

[tex]\dfrac{4x^3-3x^2+5x+6}{x+6}[/tex]

[tex]=4x^2+\dfrac{-27x^2+5x+6}{x+6}[/tex]

[tex]=4x^2-27x+\dfrac{167x+6}{x+6}[/tex]

[tex]=4x^2-27x+167+\dfrac{-996}{x+6}\\\\\\=4x^2-27x+167-\dfrac{996}{x+6}[/tex]

Hence, the solution of the division can be written as [tex]4x^2-27x+167-\dfrac{996}{x+6}[/tex].

The area of a rectangle is it's length(l)  times its width(w):  

Area = l*w

Area = (12 cm)*(10 nm) = 120 cm^2

Question :-

Answer :-

[tex] \rule {180pt} {2pt} [/tex]

Given :-

To Find :-

Solution :-

As per the provided information in the given question, we have been given that the Lenght of Rectangle is 12 cm . Breadth of Rectangle is given 10 cm . And, we have been asked to calculate the Area of Rectangle .

For calculating the Area , we will use the Formula :-

Therefore , by Substituting the given values in the above Formula :-

⇒ Area of Rectangle = Lenght × Breadth

⇒ Area of Rectangle = 12 × 10

⇒ Area of Rectangle = 120

Hence :-

The number of people that went to the amusement park consisted of 26 students and 16 adults.

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x is the number of students and y is the number of adults. The bus of 42 people paid $1080 to enter the amusement. Hence:

x + y  = 42   (1)

Also:

20x + 35y = 1080    (2)

From equation 1 and 2:

x = 26, y = 16

First, combine like terms:

4x -58 +x =2 can be rewritten as 5x - 58 =2

Next, isolate the x on one side of the equation by adding 58 to both sides:

5x = 60

Now, isolate x again by dividing by 5 on both sides of the equation:

Answer: x = 12

Answer:

It would most likely be 25 but there is no definitive way to tell if it would land on 5 at all since it is all up to chance on a spinner, unless it was computer generated then it would be probability.

Step-by-step explanation:

The number of times Camilla should expect to spin a 2 is 600.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

Given that, Camilla spins a game spinner 1800 times.

The spinner is divided into six equally spaced sections numbered 1-6.

Probability of getting 2 is 2/6

= 1/3

Spin 1800 times

1/3×1800

= 600

Therefore, the number of times Camilla should expect to spin a 2 is 600.
