Las soluciones de las ecuaciones lineales por propiedades algebraicas se listan a continuación:

7) x = 7

8) x = 16 / 7

9) x = - 1 / 4

10) x = 1 / 5

En este caso tenemos cuatro casos de ecuaciones lineales, cuya variable x debe ser despejada mediante propiedades algebraicas. A continuación, se procede a determinar las soluciones correspondientes a cada expresión:

Caso 7:

2 · (x - 1) - 5 = 14 - x

2 · x - 2 - 5 = 14 - x

2 · x - 7 = 14 - x

3 · x = 21

x = 7

Caso 8:

15 · x + 10 = 6 · x - 2 · (x - 7) + 3 · (1 - x)

15 · x + 10 = 6 · x - 2 · x + 14 + 3 - 3 · x

15 · x + 10 = x + 17

14 · x = 32

x = 32 / 14

x = 16 / 7

Caso 9:

x + 3 · (x - 1) = 6 - 4 · (2 · x + 3)

x + 3 · x - 3 = 6 - 8 · x - 12

4 · x - 3 = - 6 - 8 · x

12 · x = - 3

x = - 1 / 4

Caso 10:

6 - 3 · (x + 1) = 4 · x + 2 · (1 - x)

6 - 3 · x - 3 = 4 · x + 2 - 2 · x

3 - 3 · x = 2 · x + 2

- 5 · x = - 1

x = 1 / 5

The following equation's linear components have no solutions.

Because they contain the same variable term on one side of the equation but distinct constant values on the other, 5-4x-7-10x=-8x-4-6x-10.

A linear polynomial over a field with zero coefficients can be used to create a linear equation. The answers to such an equation are the numbers that, when the unknowns are replaced, make the equality true.

This particular situation, in which the variable is accurately referred to as the unknown, is commonly referred to as a "linear equation."

In the case of two variables, each solution can be thought of as a point's Cartesian coordinates on the Euclidean plane. The answers to a linear equation result in a line.

Given is an equation that reads 5-4x-7-10x=-8x-4-6x-10 and 14x-2=14x-14.

A linear equation has no solutions if both sides of the equation have different constant values but the same variable term.

The required length of the right rectangular prism is 18 in whose volume is 540 cu. in

Having six faces, a rectangular prism is a three-dimensional shape (two at the top and bottom and four are lateral faces). The prism's faces are all rectangular in form. There are three sets of identical faces as a result. A rectangular prism is often referred to as a cuboid because of its form. A rectangular prism may be found in everyday objects like a geometry box, notebooks, diaries, and rooms.

Rectangular prism characteristics

There are two categories into which rectangular prisms can be divided. These are:

A rectangular prism is a prism with rectangular bases. A right rectangular prism is a prism with six rectangle-shaped faces with angles that are all right angles.

Vertices of a rectangular prism = 8

Edges of a rectangular prism = 12

Faces of a rectangular prism= 6 (including bases)

total volume of the prism = 540 cubic inches.

Width = 6 in

Height = 5 in

We know volume is length * breadth* height

⇒ 540 = 5*6* length

⇒length = 18 in

The cost of the apples per pound is $1.8.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example: 42x = 10 is an equation.

From the question, We were given

9 pounds of apples.

Amount of apples eaten = 3/4 of a pound

This means,

1 pound - 3/4 pound = 1/4 pound left

Now,

The pounds of apples left:

= 8 + 1/4

= 33/4 pounds

33/4 pounds = $15

Multiply 4/33 on both sides.

1 pound = 4/33 x $15

1 pound = $1.8

Thus,

The cost of the apples per pound is $1.8.

A stem and leaf plot is a way of representing data (it might be helpful to look up a video—the organic chemistry tutor has a good one).

The column on the left shows the first digit of each number, and the column on the right is the different ones place digits.

Take the number 31. It would go at the bottom, where the 3 (from the tens place) is in the left column and the 1 (from the ones place) is in the right column.

3 would be in the first row as 03.

The pounds of fruit  he buy if he buys 3 pounds of pears and 2 pounds of apples is $16.75.

In case he buys x pounds of pears and y pounds of apples, then he will have  ($3.50x + $3.25y) number of fruits.

The concept that will be used is the concept of addition.

We were told that the Pears cost $3.50 per pound and apples cost $3 per pound from the question.

We can get the total pounds of fruits bought  by multiplying the pounds of apples  with cost per pound and then add it to the  multiplication of the pounds of blueberries and cost per pound which can e expressed as:

($3.50 x 2) =$ 7

+ (3.25 x 3) = $9.75

Then add together as

($ 7 + $9.75 )= $16.75

Answer:

La notación científica es una forma de escribir números muy grandes o muy pequeños de manera más compacta y legible. En la notación científica, se mueve el punto decimal de un número hasta que tenga una sola cifra a la izquierda del punto y luego se multiplica el número resultante por 10 elevado a una potencia de 10.

Por ejemplo, para escribir 621,000 en notación científica, podemos mover el punto decimal tres lugares a la derecha para obtener el número 6.21. Luego, podemos multiplicar este número por 10 elevado a la potencia de 3 (10^3), lo que da 6.21 x 10^3 = 6.21 x 1000 = 621,000.

Entonces, en notación científica, 621,000 se escribe como 6.21 x 10^3.

Answer:

To find the growth rate for a country with a population of 11,000,000, 320,000 births, and 650,000 deaths, you need to first calculate the natural increase in the population by subtracting the number of deaths from the number of births: 320,000 - 650,000 = -330,000. This means that there are 330,000 more deaths than births in this country.

To calculate the growth rate, you need to divide the natural increase by the total population and multiply by 100 to express the result as a percentage. In this case, the growth rate would be: (-330,000 / 11,000,000) * 100 = -3.0%. This means that the population is decreasing at a rate of 3.0% per year.

To find the growth rate for a country with 60,000 births, 50,000 deaths, 20,000 immigrants, and 10,000 emigrants, you need to first calculate the natural increase in the population by subtracting the number of deaths from the number of births: 60,000 - 50,000 = 10,000. Then, you need to add the number of immigrants to this number to get the total increase in the population: 10,000 + 20,000 = 30,000. Finally, you need to subtract the number of emigrants from this number to get the net increase in the population: 30,000 - 10,000 = 20,000.

To calculate the growth rate, you need to divide the net increase in the population by the total population and multiply by 100 to express the result as a percentage. In this case, the growth rate would be: (20,000 / 20,000,000) * 100 = 0.1%. This means that the population is increasing at a rate of 0.1% per year.

Belgium has a growth rate of 0.1%, which means that its population is increasing by 0.1% per year. To find out how many years it will take for the population to double, you need to divide the growth rate into the number 100. Since 100 / 0.1 = 1000, it will take 1000 years for Belgium's population to double if it continues to grow at a rate of 0.1% per year.

Libya is doubling its population every 19 years, which means that its population is increasing by 100% every 19 years. To find the growth rate, you need to divide the population increase (100%) by the number of years it takes for the population to double (19 years) and multiply by 100 to express the result as a percentage. In this case, the growth rate would be: (100 / 19) * 100 = 5.26%. This means that Libya's population is increasing at a rate of 5.26% per year.

In linear equation,$308 is Mr. Brown leaving a a tip .

What in mathematics is a linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.

                        Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

The amount of hotel bill= $140

He leaves 12% of the hotel bill as a tip for the housekeeping service.

Thus, the amount of tip= 12% of hotel bill

=12% of $140

= 12/100 * 140

= 12 * 14

=    168

Therefore, the total amount Mr. Chin pays, including tip =$140+$168 =$308

What are similar triangles?

Similar triangles are triangles that have constant form, however their sizes could vary. All equal triangles, squares of any facet lengths area unit samples of similar objects. In alternative words, if 2 triangles area unit similar, then their corresponding angles area unit congruent and corresponding sides area unit in equal proportion.
