Hey ! Buddy .

As the question is in Spanish . So we have provided your answer in English as well as in Spanish language .

( ¡Oye! Amigo, la pregunta es en español. Así que hemos proporcionado su respuesta tanto en inglés como en español. )

Answer:

  • Value of x is <u>36</u><u> </u>(El valor de x es <u>36</u>)

Step-by-step explanation:

In this question we have given with an equation that is<u> -6x + 71 = -4x - 1 .</u> And have to find the value of x .

( En esta pregunta hemos dado con una ecuación que es <u>-6x + 71 = -4x - 1</u> . y hay que encontrar el valor de <u>x</u> <u>)</u>

<u>Solution</u><u> </u><u>:</u><u> </u><u>-</u><u> </u>

<u>(</u><u> </u><u>Soluciones : -</u><u> </u><u>)</u>

<u>\quad   : \implies - 6x + 71 =  - 4 - 1</u>

<u>Step </u><u>1</u><u> </u><u>:</u> Subtracting 71 on both sides :

( <u>Paso 1 :</u> Restando 71 en ambos lados: )

\quad   : \implies - 6x +  \cancel{71} -  \cancel{71} =  - 4x - 1 - 71

On calculating further, We get :

( Al calcular más, obtenemos : )

\quad   : \implies - 6x =  - 4x  - 72

<u>Step </u><u>2</u><u> </u><u>:</u><u> </u>Adding 4x on both sides :

( <u>Paso </u><u>2</u><u> </u><u>:</u> Sumando 4x en ambos lados: )

\quad   : \implies - 6x + 4x =  -  \cancel{4x} +  \cancel{4x } - 72

On calculating further, We get :

( Al calcular más, obtenemos : )

\quad   : \implies  \cancel{-} 2x =   \cancel{-}72

<u>Step </u><u>3</u><u> </u><u>:</u> Dividing by 2 on both sides :

( <u>Paso </u><u>3 </u><u>:</u> Dividiendo por 2 en ambos lados: )

\quad   : \implies \frac{ \cancel{2}x}{ \cancel{2} } =   \cancel{\frac{72}{2} }

On calculating further , We get :

( Al calcular más, obtenemos : )

\quad   : \implies \:  \green{ \boxed{ \frak{x = 36}}}

  • <u>Therefore</u><u> </u><u>,</u><u> </u><u>value </u><u>of </u><u>x </u><u>is </u><u>36</u><u> </u><u>.</u><u> </u><u>(</u><u> </u>Por lo tanto , el valor de x es 36 . )

<u>Verifying</u><u> </u><u>:</u><u> </u><u>-</u><u> </u>

<u>(</u><u> </u><u>Comprobación :-</u><u> </u><u>)</u>

We are verifying our answer by substituting value of x in given equation. So ,

( Estamos verificando nuestra respuesta al sustituir el valor de x en la ecuacióndada. Asi que, )

  • -6x + 71 = -4x - 1

  • -6 ( 36 ) + 71 = -4 ( 36 ) - 1

  • -216 + 71 = -144 - 1

  • -145 = -145

  • L.H.S = R.H.S (Lado izquierdo = Lado derecho )

  • Hence, Verified. ( Por lo tanto, Verificado. )

<u>Therefore</u><u>,</u><u> our</u><u> </u><u>solution</u><u> is</u><u> correct</u><u>.</u><u> </u>

<u>(</u><u> </u><u>Por lo tanto, nuestra solución es correcta. </u><u>)</u>

Answer:

-6x+71= -4x-1

-6x+71-71=-4x-1-71

-6x=-4x-72

-6x+4x=-4x-72+4x

-2x=-72

\cfrac{-2x}{-2}=\cfrac{-72}{-2}

x=36

Hope it helps u!! ^-^

The mean age of teachers at Davis senior high school is 43.6 years. If a hypothesis test is performed, how should you interpret
Ksju [112]

Answer:

The interpretation is

   There is not sufficient evidence to support the claim that \mu = 43.6

Step-by-step explanation:

From the question we are told that

  The population mean is  \mu =  43.6 \ years

Generally

    The null hypothesis is  H_o : \mu = 43.6

Given from the question that the null hypothesis was rejected then the conclusion will be

   There is not sufficient evidence to support the claim that \mu = 43.6

Please help me! I am really struggling with this...
Alexeev081 [22]

Answer:

44°

Step-by-step explanation:

The secant- secant angle y is half the difference of the measure of its intercepted arcs, that is

\frac{1}{2}(BHF - CGJ ) = y , that is

\frac{1}{2}(156 - CGH) = 56° ( multiply both sides by 2 )

156 - CGH = 112° , thus

CGH = 156° - 112° = 44°

Answer:

3.2 km/h

Step-by-step explanation:

1. Approach

The average speed is the rate at which one travels. It can be found by diving the total distance traveled over the total time it took to cover that distance. In essence, the following formula can be used to find the average speed:

\frac{total\ distance}{total\ time}=average\ speed

In this situation, one is asked to find the difference between two people's average speed. One is given the following information:

Lena: 24 miles          1.5 hours

Ras:   36km               1 hour 15 minutes

First, convert all of the numbers into the correct units (km) and (hours). Then find the average speed for each person. Finally, subtract the smaller speed from the larger speed to find the difference in the average speeds.

1. Find Lena's average speed

The problem asks one to find the average speed in the units (km/h). However, the distance Lena covered is given in (miles). Therefore, one has to multiply it by the conversion factor (1.6) in order to convert it from (miles) to (km).

24miles * 1.6 = 38.4

Now find the average speed by using the formula:

\frac{total\ distance}{total\ time}=average\ speed

Substitute,

\frac{38.4}{1.5}\\\\=25.6

2. Find Ras's average speed

Use a similar approach to work out Ras's average speed, as was used to find Lena's average speed. Since Ras's time spent is given in both hours and minutes, one must convert it to just minutes. There are (60) minutes in an hour, thus, one can rewrite the number as the following:

1\ hour \ \ 15\ minutes= 1 \frac{15}{60}\ hours = \frac{75}{60}\ hours

Now find the average speed:

\frac{total\ distance}{total\ time}=average\ speed

Substitute,

\frac{36}{\frac{75}{60}}\\\\=28.8

3. Find the difference between the speeds

Since Ras's speed is greater, subtract Lena's speed from Ras's speed.

Ras - Lena

= 28.8 - 25.6

= 3.2
