When Keisha installed a fence along the 200-foot perimeter of her rectangular backyard, she left an opening for a gate. In the diagram below, she used x to represent the length, in feet, of the gate.
.
What is the value of x, if the equation 2(x + 60) + 2(30) = 200 represents the Perimeter for the fencing of the backyard?

When Keisha Installed A Fence Along The 200-foot Perimeter Of Her Rectangular Backyard, She Left An Opening

Answers

Answer 1

Answer:

Step-by-step explanation:

From the picture attached, equation of the perimeter of the fence of the backyard should be,

(x + 60) + (60) + 2(30) = 200

x + 2(60) + 2(30) = 200

x + 120 + 60 = 200

x + 180 = 200

x = 200 - 180

x = 20 ft

If the given equation for the perimeter for the fencing of the backyard (As given in the question) is,

2(x + 60) + 2(30) = 200

2x + 120 + 60 = 200

2x + 180 = 200

2x = 20

x = 10 ft

Answer 2

Answer:

2(x + 60) + 2(30) = 200

2x + 120 + 60 = 200

2x + 180 = 200

2x = 20

x = 10 ft

x = 2

Step-by-step explanation:

g(x) = 2x - 1

g(x) = 3

2x - 1 = 3

Add 1 to both sides;

2x = 4

Divide both sides by 2;

x = 2

Answer: x = 2

Explanation:

Set g(x) = 3

3 = 2x - 1
Add 1 to both sides
4 = 2x
Divide by 2 on both sides
x = 2

Answers

Answer:

80 heart stickers does a pack of 140 stickers

Step-by-step explanation:

The number of heart stickers in a pack of 140 stickers is 60.

Given that, a sheet of 28 stickers has star and heart stickers.

What is the ratio?

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Here, the number of star stickers in a sheet

= 28-16 =12

The ratio of star and heart stickers

= 12:16

= 3:4

Now, 3+4=7

Number of heart stickers = 3/7 ×140

= 60

Therefore, the number of heart stickers in a pack of 140 stickers is 60.

x = Horas Trabajadas 0 1 2 3 4

y = Dólares Ganados 0 3 6 9 12

La tabla anterior muestra la relación entre las horas trabajadas y el dinero en dólares, que obtuvo Juan trabajando a razón de $3.00 por hora. En esta tabla, podemos ver que el dinero ganado es igual al producto de las horas trabajadas por 3. Otra manera de decir eso es que la constante de variación o proporción es igual o 3. También se puede observar que cada vez que x aumenta en un 1, la variable y aumenta en 3. Otra manera de decir eso es que la razón de cambio es igual a 3.

En la aplicación de abajo, mueve el botón de la barra “constante de variación” a 3. Observa que los puntos de la gráfica coinciden con los valores en la tabla, y que con cada aumento de 1 en x, la variable y aumenta 3 y que la relación entre las variables es y = 3 × x .

En la aplicación de arriba, mueve el botón de la barra constante de variación a 4. Observa que los puntos de la gráfica coinciden con los valores en la tabla, y que con cada aumento de 1 en x, y aumenta 4 y que la relación entre las variables es y = 4 × x.

Si una galleta cuesta 50 centavos, la tabla anterior muestra la relación entre la cantidad de dólares y la cantidad de galletas que se puede comprar. En esta tabla, podemos ver que la cantidad de galletas se obtiene multiplicando la cantidad de dólares por 2.

En la aplicación de arriba, mueve el botón de la barra constante de variación a 2. Observa que los puntos de la gráfica coinciden con los valores en la tabla, y que con cada aumento de 1 en x, la variable y aumenta en 2 y que la relación entre las variables es y = 2 × x

.

En todas estas relaciones de los ejemplos anteriores, una variable es igual a otra variable multiplicada por una constante distinta de cero. Estas relaciones se conocen como proporciones directas o variaciones directas.

Definición

Dadas dos variables x y y, los enunciados:

y varía directamente como x,

y es directamente proporcional a x y

y es proporcional a x

todos significan que y = kx, para algún número real fijo k.

Al número k se le llama la constante de variación o constante de proporcionalidad. El valor de k también representa la razón de cambio de la relación. Es decir, cada aumento de 1 en x va a corresponder a un aumento de k en y.

Pasos para hallar la Fórmula para Relaciones de Variación Directa

Las relaciones de variación directa tienen la forma y = kx donde x y y son variables y k es una constante distinta de cero. La fórmula para una relación de variación directa se puede hallar mediante los siguientes pasos:

Paso 1: Traducir el enunciado a una fórmula de variación directa.

y es directamente proporcional a x significa

y =k·x

Paso 2: Sustituir las variables conocidas para encontrar k.

Paso 3: Sustituir k y escribir la fórmula.

Ejemplos

Ejemplo 1

u es proporcional a v. Si u = 16 cuando v = 4, escribe la fórmula para la relación entre u y v.

Paso 1: Traducir el enunciado a una fórmula de variación directa.

u es proporcional a v significa

u =k·v

Paso 2: Sustituir valores conocidos para encontrar k.

16 = k· 4

k=164=4

Paso 3: Sustituir k y escribir la fórmula.

u =4v

Conclusión: la fórmula para expresar la relación entre u y v es u =4v

Ejemplo 2

p varía directamente como z. Si p = 210 cuando z = 200, escribe la fórmula para expresar la relación entre p y z .

Paso 1: Traducir el enunciado a una fórmula de variación directa.

p varía directamente como z significa

p = k·z

Paso 2: Sustituir valores conocidos para encontrar k.

210 = k· 200

k=210200=1.05

Paso 3: Sustituir k y escribir la fórmula.

Answer:

she took 13 classes that were worth 3 credits

Step-by-step explanation:

well we know that some of the classes are worth 3 and some are worth 4 and that all of these together = 59 so your first equation would be

3x+4y=59

x  would be the number of classes worth 3 credits and y would be the number of classes worth 4 credits.

then it says the total number of classes that they took was 18 so we know that

x + y =18.

you want to solve for the number of 3 credit classes so lets go ahead and get rid of the y values. SO you need you multiply the x+y equation by 4

4x+4y=72

then subtract 4x+4y=72  from 3x+4y=59 to get

-x = -13

and then x is a negative so you need to divide -1 from both sides and you get that she took 13 classes that were worth 3 credits.

You go shopping and spend $264 on shirts and shorts. You purchase a total of 9 items. Each shirt costs $24 and each pair of shorts cost $32. How many of each did you buy?

Answers

Answer:

3 shirts, 6 shorts

Step-by-step explanation:

A total of $264 is spent during shopping on shirts and shorts

Each shirt costs $24

Each shorts cost $32

Therefore the quantity of shirts and shorts bought can be calculated as follows

24× 3= 72

32×6= 192

192+72= 264

Hence 3 shirts and 6 shorts were bought
