An algebraic expression (or) a variable expression is a combination of terms by operations such as addition, subtraction, multiplication, and division. For example, let's look at the expression 5x + 7.

Algebraic Expression:

Algebraic expressions are mathematical expressions that result when you perform operations such as addition, subtraction, multiplication, and division on variables and constants. For example, let's say James and Natalie were playing with matches and wanted to create a pattern of numbers in matches. James played four games and formed No. 4. Natalie added three more games and two he formed a pattern of four. They realized they could add 3 matches to each round to get an extra '4'. From this, they concluded that, in general, 4 + 3 (n-1) double crochet stitches are required to create n 4 patterns. Here 4+ 3(n-1) is called an algebraic expression. To solve a linear equation with one variable, use the transpose method. Follow this procedure to perform the same operations on both sides of the equal sign. That is, perform operations to isolate variables.

Example:

5x + 7 = 32

Subtract 7 from both sides

⇒ 5x = 25

Divide both sides by 5

⇒ x = 5

⇒ 5x = 25

Divide both sides by 3

⇒ 2y – 12 = 24

Add 12 to both sides

⇒ 2y = 36

Divide both sides by 2

⇒ y = 18.

Answer:

x = 2

y = 5

Step-by-step explanation:

A system of equations is a set of two or more equations that contain multiple variables. To solve a system of equations, you can use different methods such as substitution, elimination or graphing.

The given system of equations is:

y = 2x + 1

y = x + 3

We are trying to find the x and y values that make both equations true at the same time.

One way to solve this system is to use the substitution method, by replacing one of the variables in one equation with the other equation.

Let's replace y from the second equation with the first equation:

x + 3 = 2x + 1

Subtract x from both sides:

3 = x + 1

Subtract 1 from both sides:

2 = x

Now that we have the value of x, we can substitute it back into either one of the original equations to find the value of y.

Let's substitute it back into the first equation:

y = 2(2) + 1

y = 5

So the solution to this system of equations is x = 2 and y = 5. It means that both equations are true when x = 2 and y = 5

You can also check your solution by substituting x and y back into the equations and see if both of them are true.

The probability that a pupil would excel in math's or English = 0.691

A probability is a numerical representation of the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages range from 0% to 100% can be used to describe probabilities.

120 students are enrolled in total. Let A represent the scenario in which a student receives a mathematics award, and B represent the scenario in which a student receives an English award. The odds of these events are as follows:

48 won awards for mathematics

78 won awards for English.

14 students  won awards for mathematics and English.

P(A) = 48/120

P(B) = 78/120

P(A ∩ B) = 14/120

Due to the fact that 14 students shared the honors from both events, the following equation should be written for overlapping sets:

P(A or B ) =   P(A) + P(B)  -  P(A ∩ B)

                 = 48/120 + 78/120 - 14/120

B. The y-intercept does not make sense in this situation, as a savings account balance cannot be negative. It is not possible to have negative dollars in a savings account.

C. Tasha's possible error is that she may have misinterpreted the y-axis to represent a negative balance, when in reality it represents zero balance. The y-intercept represents the initial balance of the account, which should be zero or a positive number. This error can be corrected by starting the y-axis from zero and making sure the y-intercept is positioned at a positive value.

Substitute y = 0 and solve for x to find the x-intercept, and do the same for the y-intercept.

Examples on the Y Intercept Using the y-intercept formula, we can find the y-intercept of a function by substituting x = 0 and solving for y; consequently, the given function lacks a y-intercept. 2nd Example: Find the value of "a" if the y-intercept of a function y = a (x - 1) (x - 2) (x - 3) is (0, 12).

We can solve for the y-intercept in the slope-intercept equation y=mx+b by first determining the slope between two points on a line and then writing an equation for that line.

The slope-intercept form is used to write the line's equation, which looks like this: y is equal to mx + b, where m is the slope and b is the y-intercept. We can see that the line has a slope of 6 in our equation, which is y = 6x + 2.

Method 1: Each exterior angle of a regular polygon is equal to 180-108°, or 72°, if each internal angle is 108°.Regardless of the number of sides, any figure's outer angles add up to 360 degrees.

The figure has 360/72 or 5 sides since each outer angle is 72 degrees. Therefore, the polygon is a standard pentagon. Answer.

Method 2: Using n isosceles triangles, a regular polygon with n sides is created. 54° is the basis angle, or 108/2. Each vertical angle is equal to 2*36°, or 72°, which is the semi-vertical angle of 90-54°. 360/72 equals 5, the number of isosceles triangles. Therefore, the polygon is a standard pentagon.

Como la cuerda está formando un ángulo de 30 grados con la horizontal, la componente de la fuerza en la dirección de la cuerda se calcula utilizando el coseno del ángulo: 86.6 N.

Para calcular el valor de la normal y la fuerza de rozamiento, primero debemos calcular la componente de la fuerza de gravedad que actúa en dirección perpendicular a la superficie de apoyo. La componente de la gravedad en dirección perpendicular se calcula utilizando el seno del ángulo formado por la cuerda con la horizontal (30º):

F_normal = F_grav * sen(30º)

Donde F_grav es la fuerza de gravedad del cuerpo, que se calcula como:

F_grav = m * g

Donde m es la masa del cuerpo (40 kg) y g es la aceleración debida a la gravedad (9.8 m/s²)

Por lo tanto,

F_normal = (40 kg) * (9.8 m/s²) * sen(30º) = 392 N

La fuerza de rozamiento se calcula utilizando la fórmula:

F_fric = μ * F_normal

Donde μ es la coeficiente de rozamiento estático entre el cuerpo y la superficie de apoyo. Como no se especifica el valor del coeficiente de rozamiento, no se puede calcular la fuerza de rozamiento.

La tensión en la cuerda es igual a la fuerza neta en la dirección de la cuerda. Como la cuerda está formando un ángulo de 30 grados con la horizontal, la componente de la fuerza en la dirección de la cuerda se calcula utilizando el coseno del ángulo:

From the given equations, we can see that the coefficients of x and y are the same in both equations, which is 6x. The constant terms, however, are different. The first equation has a constant term of -8, while the second equation has a constant term of -16.

To make the equations equivalent, we need to make the constant terms the same. We can do this by dividing the second equation by 2. This gives us 6 ky - 8 = 0.

Answer:

Length of Carla's living room is 20 feet

Step-by-step explanation:

The perimeter of a rectangle is 2(L + W)
In the case of both dining and living rooms, we are given the widths as dining room width = 18, living room width = 12 and asked to calculate living room length from the information given

Let x be the length of the dining room and y the length of the living room

Perimeter of dining room = 2(18 + x)

Perimeter of living room = 2(12 + y)

Since these are equal
2(18 + x) = 2(12 + y)

=> 18 + x = 12 + y

Subtract x from both sides:
18 = 12 + y - x

Subtract 12 from both sides:
18 - 12 = y - x

Simplifying and rearranging terms we get

- x + y = 6  [1]

We are also given that:
The length of her dining room is 1 foot less than 3/4 the length of her living room.

This mathematically translates to:
[tex]x = \dfrac{3}{4}y - 1[/tex]

which can be re-written as

[tex]x - \dfrac{3}{4} = -1 \; \cdots[2][/tex]

So the two equations are

[tex]- x + y = 6 \;\cdots [1][/tex]

[tex]x - \dfrac{3}{4}y = - 1 \; \cdots [2][/tex]

Notice that the coefficients of x are the same(1) but with opposite signs

Add [1] and [2]

[tex](-x + y) +(x - \dfrac{3}{4}y) = 6 - 1\\\\-x + x + y - \dfrac{3}{4}y = 5\\\\\dfrac{1}{4}y = 5\\\\y = 20\\\\[/tex]

So the length of the living room is 20 feet

(If you wanted to find the length of the dining room, substitute 20 into equation 1 to get -x + 20 = 6 which will give x = 14 and is the length of the dining room)
