It seems that the slope of this line is 1/5, yet none of the answers correspond to this. Double-check by finding two points on the line, and use the slope formula: (y2-y1/x2-x1). Also, remember that slope is rise/over run. I hope this can guide you!

Answer: the answer is not included in the options

Step-by-step explanation:

The slope of the line can be depicted by the following formulas: 1. Rise/run 2. Y1-y2/ x1-x2

If we were to use the second formula and “plug” in numbers for the variables, the slope we calculate is less than 1

Answer:

Ok, primero Agustín camina a 5km/h.

Cuando el recorre 7km, el regresa.

El tiempo en el que sucede esto es a:

7km/5km/h = 1.4 h

La ecuación para Agustín es:

A(t) = 5km/h*t                                     para  0h ≤ t  ≤ 1.4h           (ida)

A(t) = 7km -  5km/h*(t - 1.4h)              para 1.4h ≤ t.                     (vuelta)

Hacemos lo mismo para Barbara:

7km/3km/h = 2.5h

La ecuación para ella es:

B(t) = 3km/h*t                                    para 0h ≤ t  ≤ 2.5h              (ida)

B(t) = 7km -  3km/h*(t - 2.5h)              para 2.5h ≤ t.                     (vuelta)

a)  ¿a qué distancia de la partida se encuentra con Bárbara?

Tenemos que ver cuando A(t) = B(t).

Para ello comparamos la vuelta de Agustín con la ida de Barbara.

7km -  5km/h*(t - 1.4h) = 3km/h*t  

7km - 5km/h*T + 7km = 3km/h*T

14km = 8km/h*t

14/8 h = 1.75h = t.

Entonces la posición en la que se encuentran es:

B(1.75h) = 3km/h*1.75h = 5.25km

Ellos se encuentran a 5.25 kilómetros de el punto de partida.

b)  Si en el momento del encuentro también Bárbara emprende el regreso

(Es decir, en este momento Barbara comienza a regresar).

Entonces ella para regresar al punto de inicio tiene que recorrer 5.25km con una velocidad de 3km/h.

Tb = 5.25km/3km/h = 1.75h

Barbara tarda 1.75 horas en regresar.

Agustín también tiene que recorrer 5.25 km para regresar, pero su velocidad es 5km/h.

Ta = 5.25km/5km/h = 1.05h.

La diferencia entre los tiempos es:

Tb - Ta  =1.75h - 1.05h = 0.7h

Entonces Barbara llega al punto de partida 0.7 horas después que Agustín.

Pero queremos esto en minutos.

1 hora = 60 minutos.

0.7 horas = 0.7*(60 min) = 42min

Barbara llega 42 minutos después que Agustín.

Answer: 40

Step-by-step explanation: 50x0.8=40

Okay, maybe im wrong? But i dont see how its 4 thats more than half.

Rodger can do 46 pushups.

50 * 0.92 = 46

Edit: To better clarify, 0.92 is from 1.00 - 0.08.  

... 8 percent fewer than 100 percent is 92 percent; 1.00 - 0.08 = 0.92

Keep in mind that:

1.00 = 100%

0.08 = 8%

0.92 = 92%

After finding this you may multiply 50 * 0.92 to get 46.

Answer:

x = -6

Step-by-step explanation:

Simplifying

5x + 7 = 3x + -5

Reorder the terms:

7 + 5x = 3x + -5

Reorder the terms:

7 + 5x = -5 + 3x

Solving

7 + 5x = -5 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

7 + 5x + -3x = -5 + 3x + -3x

Combine like terms: 5x + -3x = 2x

7 + 2x = -5 + 3x + -3x

Combine like terms: 3x + -3x = 0

7 + 2x = -5 + 0

7 + 2x = -5

Add '-7' to each side of the equation.

7 + -7 + 2x = -5 + -7

Combine like terms: 7 + -7 = 0

0 + 2x = -5 + -7

2x = -5 + -7

Combine like terms: -5 + -7 = -12

2x = -12

Divide each side by '2'.

x = -6

Simplifying

x = -6

The solution to the equation 5x + 7 = 3x - 5 is x = -6.

We have,

To solve the equation 5x + 7 = 3x - 5, we need to isolate the variable x on one side of the equation.

Here's how we can do that:

Start by subtracting 3x from both sides of the equation to move all the x terms to one side:

5x + 7 - 3x = 3x - 5 - 3x

Simplifying, we get:

2x + 7 = -5

Next, subtract 7 from both sides of the equation to isolate the term with x:

2x + 7 - 7 = -5 - 7

Simplifying, we get:

2x = -12

Now, to solve for x, we divide both sides of the equation by 2:

(2x)/2 = (-12)/2

Simplifying, we get:

x = -6

Thus,

The solution to the equation 5x + 7 = 3x - 5 is x = -6.

Answer:

Step-by-step explanation:

Answer:

[tex]m=20c[/tex]

Step-by-step explanation:

Let m represent the total money collected and c represent the amount of cars washed.

We know that the money collected is directly proportional to the number of cars washed. So, we can write the following equation:

[tex]m=kc[/tex]

Where k is a constant.

We know that the money collected after 7 car washes is $140. So, let's find our k by substituting 140 for m and 7 for c. This yields:

[tex]140=7k[/tex]

Find k. Divide both sides by 7:

[tex]k=20[/tex]

So, the value of k is 20.

We can now substitute k back into our direct variation equation:

[tex]m=20c[/tex]

This means that every car costs $20 to wash.

And we're done!
