Answer:

x = -17

Step-by-step explanation:

7(2x + 3) = 12x - 13

Distribute

7*2x +7*3 = 12x-13

14x +21 = 12x-13

Subtract 12x from each side

14x-12x+21 = 12x-12x-13

2x+21 = -13

Subtract 21 from each side

2x+21-21 = -13-21

2x = -34

Divide by 2

2x/2 = -34/2

x = -17

Answer:

8 Minutes

Step-by-step explanation:

since we are trying to find how many minutes have passed we first need to find how much substance was used during the time. we can do that by subtracting the leftover substance from the amount we started with.

666-562 = 104

Now that we know how much substance was used we can then use our conversion rate (13 per minute) and find how many minutes have passed by dividing.

104 / 13 = 8

Answer:

Step-by-step explanation:

Convert mixed fraction to improper fraction.

[tex]4\frac{1}{2}[/tex] ÷ [tex]1\frac{1}{4} =[/tex] [tex]\frac{9}{2}[/tex] ÷ [tex]\frac{5}{4}[/tex]

In fraction division, Use KCF method

K - Keep the first fraction

C - Change the ÷ operation to  * operation

F - Flip the second fraction

  [tex]= \frac{9}{2}*\frac{4}{5}\\\\= \frac{9}{1}*\frac{2}{5}\\\\=\frac{18}{5}\\\\= 3\frac{3}{5}[/tex]

Answer:

n=5

Step-by-step explanation:

7n+2=4n+17

Subtract 2 from both sides

7n=4n+15

Subtract 4n

3n=15

Divide by 3

n=5

I hope it helps!

Answer:

7n+2=4n+17

7n+2−2=4n+17−2

7n=4n+15

7n−4n=4n+15−4n

3n=15

3n/3=15/3

n=5

Step-by-step explanation:

1/(x + 1) consists of 1 factor, 1/(x + 1)

1/[a(x + 1)] consists of two factors, 1/a and 1/(x + 1)

The LCM is 1/[a(x + 1)]

The LCD is a(x + 1)

El ejercicio completo es el siguiente:

Mercedes tiene una habilidad increíble al encontrar el número que falta; ella solo suma y ya tiene la respuesta correcta.

¿Cuál es el valor de x?

32 10 41

22 10 33

53 16 62

25 (x) 25

A) 10

B) 11

C) 12

D) 13

E) 14

Answer:

La  respuesta correcta es E: 14

Step-by-step explanation:

El ejercicio nos da una pista importante: solo sumar, así que al  mirar la ubicación de la variable x podemos deducir que los valores del centro son el resultado de una suma, ahora para saber si es cierto ,debemos hacer la prueba,entonces empezamos a sumar los dígitos por separado  de los valores dados ;

32 10  41 = 3+2+4+1 esto es igual a 10 el valor del centro

22 10  33= 2+2+3+3 esto es igual a 10 el valor del centro

53 16 62 = 5+3+6+2 esto es igual a 16 el valor del centro

Por lo tanto para hallar el valor de x debemos hacer lo mismo:

25   x   25 = 2+5+2+5 esto es igual 14

Entonces nos queda : 25 14 25= 2+5+2+5 igual a 14

Step-by-step explanation:

A is positioned at (7, - 5 )

Answer:

? =30

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp / hyp

sin ? = 25/50

Taking the inverse sin of each side

sin ^-1( sin ?) = sin^-1 ( 1/2)

? =30

Given:

The amount of money in Joel’s account is:

[tex]j(x)=25+3x[/tex]

The amount of money in Kevin’s account is:

[tex]k(x)=15+2x[/tex]

To find:

The function that correctly represents how much more money, in dollars, is in Joel’s account than in Kevin’s account x weeks after the start of the year.

Solution:

We need to find the difference between the function j(x) and function k(x).

[tex]j(x)-k(x)=(25+3x)-(15+2x)[/tex]

[tex](j-k)(x)=25+3x-15-2x[/tex]

[tex](j-k)(x)=(25-15)+(3x-2x)[/tex]

[tex](j-k)(x)=10+x[/tex]

Therefore, the correct option is D.

Answer:

Step-by-step explanation:

v(x) - W(x) = x² + 2x  - 4 - [x³ + 2x² + x + 5]

                = x² + 2x - 4 - x³ - 2x² -x - 5

                = x² - 2x² - x³ + 2x - x -4 - 5

               =  -x² - x³ + x - 9

Answer:

x³ - 3x² + x - 9

Step-by-step explanation:

V(x) - W(x) =

- x² + 2x - 4 - (- x³ + 2x² + x + 5) ← distribute parenthesis by - 1

= - x² + 2x - 4 + x³ - 2x² - x - 5 ← collect like terms

= x³ - 3x² + x - 9

Answer:

[tex]\text{B. }p(x)=x(x-2)(2x-7)[/tex]

Step-by-step explanation:

The zeroes of a function occur when the function crosses the x-axis. The function shown crossed the x-axis at [tex]x=0[/tex], [tex]x=2[/tex], and [tex]x=3.5[/tex]. These values of [tex]x[/tex] should produce an output of 0 when plugged into the function.

Therefore, the equation of the function graphed is [tex]\boxed{\text{B. }p(x)=x(x-2)(2x-7)}[/tex]

Answer:

E. None of these

Step-by-step explanation:

Using the angle 43, we see that we will use Cos to find x.

This is because the sides are the adjacent and the hypotenuse

Cos (43) = 14/x

Multiply both sides by x

X (cos (43)) = 14

Then divide both sides by (cos(43))

x = 14 / cos(43)

Plug it into the calculator you get:

x = 25.22

Since this is not an answer choice, the answer is E. None of these

Answer:

x=11

Step-by-step explanation:

The angles given are alternate exterior angles and alternate exterior angles are equal if the lines are parallel

5x+9 = 6x-2

Subtract 5x from each side

5x+9-5x = 6x-2-5x

9 = x-2

Add 2 to each side

9+2 =x-2+2

11=x

Now,

5x + 9 ( vertically opposite angle )

Then,

5x + 9 = 6x - 2 ( corresponding angle )

x = 11

Answer:

[tex]y = \sqrt{\frac{x- a}{2b}}[/tex]

Step-by-step explanation:

Step 1:  Make y the subject of this formula

[tex]x- a = a - a - 2by^{2}[/tex]

[tex]\frac{x- a}{2b} = \frac{2by^{2}}{2b}[/tex]

[tex]\sqrt{\frac{x- a}{2b}} = \sqrt{y^{2}}[/tex]

[tex]\sqrt{\frac{x- a}{2b}} = y[/tex]

Answer:  [tex]y = \sqrt{\frac{x- a}{2b}}[/tex]

Answer:

FS = 48

Step-by-step explanation:

The distance from the vertex to the centroid is twice the distance from the centroid to the midpoint, so

FB = 2 BS = 2 × 16 = 32

Then

FS = FB + BS = 32 + 16 = 48

Step-by-step explanation:

some of your answer options were not copied well in here.

so, I tell you the right information and how would sure it, and you need to pick the right option on your end :

the inequality is

5x + 3 <= 28

and based on that

5x <= 25

x <= 5
