Solve for X please help I do not understand !

Answer:

x=7

Step-by-step explanation:

5(2x-5) = 10x-25

1) add 25 to both sides

10x+25=10x      6x+3+25=6x+28

10x=6x+28

2) subtract 6x from both sides

10x-6x=4x      6x+28-6x=28

4x=28

3) divide by 4 from both sides

4x/4=x      28/4=7

x=7

The value of y in the expression -5(2x - 5) = 6x + 3 is 22/16

According to the given question

We have an equation in one variable

⇒  -5(2x - 5) = 6x + 3

For finding the value of x solve the above equation by adding and subtracting the like terms.

So, -5(2x - 5) = 6x + 3

⇒ -5 x 2x + 5 x 5 = 6x + 3

⇒ -10x + 25 = 6x + 3

⇒  25 - 3 = 6x + 10x

⇒  22 = 16x

⇒ x = 22/16

Hence, the value of y in the expression -5(2x - 5) = 6x + 3 is 22/16

Answer:

Q9:D

Step-by-step explanation:

Q9:for two graphs to be perpendicular, the product of their gradients has to be -1

multiplying the gradients of the equation in the question and the equation in option "D", we get -1 hence D is correct

a) El coste total es directamente proporcional al número de estudiantes.

b) Existe una relación directa entre el coste total y el número de estudiantes al existir una constante de proporcionalidad.

c) La constante de proporcionalidad tiene un valor de 15 y representa el precio de ingreso de cada estudiante al zoológico.

d) El coste total por 120 estudiantes es $ 1,800. 95 estudiantes cuestan $ 1,425.

a) Sea y el coste total pagado para una excursión en el zoológico de la ciudad, en pesos, y x el número de estudiantes que visita el zoológico. Existe una relación directa entre las dos variables si la siguiente expresión es satisfecha:

y = k · x

Donde k es la constante de proporcionalidad, en pesos por estudiante.

A continuación, comprobamos si la relación de proporcionalidad directa existe:

Año 2.010

k₁ = 1260 / 84

k₁ = 15

Año 2.011

k₂ = 1050 / 70

k₂ = 15

Año 2.012

k₃ = 1395 / 93

k₃ = 15

Puesto que k₁ = k₂ = k₃, el coste total es directamente proporcional al número de estudiantes.

b) Existe un relación de proporcionalidad directa debido a la existencia una única constante de proporcionalidad.

c) La constante de proporcionalidad es igual a 15 y representa el costo por estudiante.

d) Si sabemos que y = 15 · x y x = 120, entonces el coste total es:

y = 15 · 120

y = 1800

El coste total es de $ 1,800.

Ahora, si sabemos que y = 15 · x, y = 1,425, entonces el número de estudiantes que ingresan es:

1,425 = 15 · x

x = 1,425 / 15

x = 95

95 estudiantes tienen un coste total de $ 1,425.

The required equation is x+4y-9 = 0.

What is an equation?

Algebra is concerned with two types of equations: polynomial equations and the particular case of linear equations. Polynomial equations have the form P(x) = 0, where P is a polynomial, while linear equations have the form ax + b = 0, where a and b are parameters, when there is only one variable. To solve equations from either family, algorithmic or geometric approaches derived from linear algebra or mathematical analysis are used. Algebra also investigates Diophantine equations with integer coefficients and solutions. The approaches employed are unique and derive from number theory. In general, these equations are complex; one frequently searches just for the existence or lack of a solution, and, if they exist, the number of solutions.

The equation is formed below

(y-2) = {(1-2)/(3+1)} (x+1)

or, y-2 = - 1/4 (x+1)

or, 4(y-2) = -1(x+1)

or, 4y - 8 = 1 - x

or, x+4y-9 = 0

Hence, the required equation is x+4y-9 = 0.

For the new coordinates of point A, that is A' = (x', y'), we have:

x' = 2 . cos (180º) = 2 . (-1) = -2

y' = 10 . cos (180º) = -10

The same happens to the other points. So, for B we have :

x' = 3 . (-1) = -3

y' = -4 . (-1) = 4

And for C:

x' = -3 . (-1) = 3

y' = 1 . (-1) = -1

Therefore, the new coordinates will be:

A'(-2, -10)

B'(-3, 4)

The equation for the given statement is (x + 2) = 2 × 6.

We have to find the equation of the given statement:

As the sum of x and 2 is equal to twice as much as 6.

So from the above, we have an equation

(x + 2 ) = 2 × 6

After removing the bracket part on the left side and multiplying at the right side we have:

x + 2 = 12

Now we have the value of x.

x = 10

(e) The area of triangle H is 4/9 times the area of triangle G.

(f) The area of triangle B is 9/16 times the area of triangle H.

(a) Triangle G and Triangle F

Consider triangle F,

The height of the triangle is 8.

The base of the triangle is 6.

The hypotenuse of the triangle is 10.

Area of ΔF = ( 1/2 ) × b × h = ( 1/2 ) × 6 × 8 = 24 square units.

Consider triangle G,

The height of the triangle is 4.

The base of the triangle is 3.

The hypotenuse of the triangle is 5.

Area of ΔG = ( 1/2 ) × b × h = ( 1/2 ) × 3 × 4 = 6 square units.

Therefore,

Area of ΔF = 4 × Area of ΔG

(b) Triangle G and Triangle B

Consider triangle G,

The area of the triangle is:

Area of ΔG = ( 1/2 ) × b × h = ( 1/2 ) × 3 × 4 = 6 square units.

Consider triangle B,

The height of the triangle is 2.

The base of the triangle is 3/2.

The hypotenuse of the triangle is 5/2.

Area of ΔB = ( 1/2 ) × b × h = ( 1/2 ) × 3/2 × 2 = 3/2 square units.

Now, 4 × 3/2 = 6

Therefore,

Area of ΔG = 4 × Area of ΔB

Area of ΔB = 1/4 × Area of ΔG

(c) Triangle B and Triangle F

Consider triangle B,

Area of ΔB = ( 1/2 ) × b × h = ( 1/2 ) × 3/2 × 2 = 3/2 square units.

Consider triangle F,

Area of ΔF = ( 1/2 ) × b × h = ( 1/2 ) × 6 × 8 = 24 square units.

Now, 16 × 3/2 = 24

Therefore,

Area of ΔF = 16 × Area of ΔB

(d) Triangle F and Triangle H

Consider triangle F,

Area of ΔF = ( 1/2 ) × b × h = ( 1/2 ) × 6 × 8 = 24 square units.

Consider triangle H,

The height of the triangle is 8/3.

The base of the triangle is 2.

The hypotenuse of the triangle is 10/3.

Area of ΔH = ( 1/2 ) × b × h = ( 1/2 ) × 2 × 8/3 = 8/3 square units.

Now, 9 × 8/3 = 24

Therefore,

Area of ΔF = 9 × Area of ΔH

Area of ΔH = 1/9 ×  Area of ΔF

(e) Triangle G and Triangle H

Consider triangle G,

Area of ΔG = ( 1/2 ) × b × h = ( 1/2 ) × 3 × 4 = 6 square units

Consider triangle H,

Area of ΔH = ( 1/2 ) × b × h = ( 1/2 ) × 2 × 8/3 = 8/3 square units.

Now,

9/4 × 8/3 = 6

Therefore,

Area of ΔG = 9/4 × Area of ΔH

Area of ΔH = 4/9 × Area of ΔG

(f) Triangle H and Triangle B

Consider triangle H,

Area of ΔH = ( 1/2 ) × b × h = ( 1/2 ) × 2 × 8/3 = 8/3 square units

Consider triangle B,

Area of ΔB = ( 1/2 ) × b × h = ( 1/2 ) × 3/2 × 2 = 3/2 square units

Now,

16/9 × 3/2 = 8/3

Therefore,

Area of ΔH = 16/9 × Area of ΔB

The required linear equation is 100x + 140 y = 500.

If an equation is written in the form ax + by + c=0, where a, b, and c are real integers and the coefficients of x and y, i.e., a and b, respectively, are not equal to zero, then it is said to be a linear equation in two variables. Examples of two-variable linear equations are 10x+4y = 3 and -x+5y = 2.

Therefore, a linear equation in two variables is any equation that can be written in the form ax + by + c = 0, where a, b, and c are real values, and a and b are not equal to zero. This implies that you can come up with a ton of these equations. Solution: It is possible to write 2x + 3y = 4.37 as 2x + 3y - 4.37 = 0.

where m is the slope

          (x,y) is the point passing by the line

           b is the intercept

So , now let us substitute the known values in the above equation
