un hotel tiene habitaciones dobles y sencillas. dispone en total de 50 habitaciones y 87 camas ¿cuántas habitaciones tiene cada
Alex777 [14]

Answer:

En el hotel hay 13 habitaciones sencillas y 37 habitaciones dobles.

Step-by-step explanation:

Un sistema de ecuaciones lineales es un conjunto de dos o más ecuaciones de primer grado, en el cual se relacionan dos o más incógnitas.

Resolver un sistema de ecuaciones consiste en encontrar el valor de cada incógnita para que se cumplan todas las ecuaciones del sistema.

En este caso, las variables que se definen son:

  • x: habitaciones simples
  • y: habitaciones dobles

Entonces, el hotel dispone en total de 50 habitaciones, por lo que se plantea la ecuación:

x + y= 50

El hotel dispone de 87 camas. La cantidad de camas por habitación puede ser expresada mediante:

x + 2*y= 87

Entonces el sistema de ecuaciones a resolver es:

\left \{ {{x+y=50} \atop {x+2*y=87}} \right.

El método de sustitución consiste en despejar o aislar una de las incógnitas, por ejemplo x , y sustituir su expresión en la otra ecuación. De este modo, obtienes una ecuación de primer grado con la otra incógnita,  y . Una vez resuelta, calculas el valor de  x  sustituyendo el valor de  y ya conocido.

En este caso, despejando x de la primer ecuación:

x= 50 -y

y reemplazando en la segunda ecuación obtienes:

50 -y + 2*y=87

-y + 2*y=87 -50

y= 37

Reemplazando en la expresión x= 50 -y obtienes:

x= 50 -37= 50-37

x= 13

Recordando que x representa la cantidad de habitaciones sencillas e y la cantidad de habitaciones dobles, <u><em>en el hotel hay 13 habitaciones sencillas y 37 habitaciones dobles.</em></u>

(9^3)^3 = ____<br><br> A) 9^0<br> B) 9^6<br> C) 9^9<br> D) 81
stepan [7]
<h2>Hello!</h2>

The answer is:

The correct option is:

C) (9^{3})^{3}=9^{9}

<h2>Why?</h2>

To solve the problem, we need to remember the power of a power property, it's defined by the following way:

(a^{m})^{n}=a^{m*n}

When we have a power of a power, we need to keep the base and then, the new exponent will be the product between the two original exponents.

So, we are given the expression:

(9^{3})^{3}

Then, calculating we have:

(9^{3})^{3}=9^{3*3}=9^{9}

Hence, we have that the correct option is:

C) (9^{3})^{3}=9^{9}

Have a nice day!

lesya692 [45]

Answer:

16.61+n=37 and p= 20.39

Step-by-step explanation:

Since Valentina has 37 dollars alreay, then that is the total amount the she has. When she spend 16.61, you will have to subtract that with 37. With p, you will put a + by it because it should that she bought additional item too. With this, you should get p=20.39
