Un hotel tiene 120 habitaciones, entre dobles i individuales. Si la cuantidad de camas son de 195, cuantas habitaciones dobles hay? Y individuales?

Answers

Answer 1

Answer:

45 individuales y 75 dobles.

Step-by-step explanation:

Para saber esto, debemos plantearlo por medio de un sistema de ecuaciones. En este caso las incógnitas serían el tipo de habitación, es decir, una será la habitación doble, y la otra la individual.

X: habitaciones individuales

Y: habitaciones dobles

Sabiendo eso, sabemos que sumando ambos tipos de habitaciones, dan el total de 120, por tanto, la primera ecuación será:

x + y = 120  (1)

Para la segunda ecuación, sabemos que hay 195 camas en total, que deben distribuirse en los dos tipos de habitaciones, en una habitación doble van 2 camas, mientras que en una individual va 1, por tanto:

x + 2y = 195   (2)

Ahora que tenemos las dos ecuaciones, solo resta resolverlo por alguno de los métodos conocidos de sistema de ecuaciones. En este caso, como las ecuaciones son sencillas podemos usar el método de reducción.

En la siguiente foto, está el procedimiento.

Answers

Answer:

y= -5/2x + 3/2

Step-by-step explanation:

(3,-6). y=mx+b or -6=-5/2 × 3+b, or solving for b: b=-6-(-5/2)(3). b=3/2.

(-1,4). y=mx+b or 4=-5/2 × -1+b, or solving for b: b=4-(-5/2)(-1). b=3/2.

Plugging in the two points, hence y= -5/2x + 3/2

i’m pretty sure it’s A but i know it’s also D

The triangles ΔABC ≈ ΔBDC and ΔABC ≈ ΔADB are similar triangles. Then the correct options are B and C.

What is the triangle?

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

In a right-angle triangle, the measure of one angle will be 90 degrees.

If any two angle of the triangles are congruent, then the triangles will be a similar triangle.

In triangle ΔABC and ΔADB, we have

∠A = ∠A (common angle)

∠B = ∠D = 90° (right angle)

Then the triangle ΔABC and ΔADB are similar triangles.

In triangle ΔABC and ΔBDC, we have

∠C = ∠C (common angle)

∠B = ∠D = 90° (right angle)

Then the triangle ΔABC and ΔBDC are similar triangles.

Then the correct options are B and C.

The diagram is given below.

What would be the best method to use in order to solve the following quadratic equation?
X^2 - 3x = 10

Answers

Answer:

Use the x method

Step-by-step explanation:

Move the 10 over to the other side and get x^2 - 3x -10 = 0 and solve by finding two numbers that add up to negative 3 but multiply to -10 which would be -5 and 2 so the binomials are (x-5)(x+2)

Answer:

x^2 - 3x = 10

Step-by-step explanation:

Move all terms to the left side.

Use the sum product pattern.

Factor (x-5)(x+2) = 0

Create two separate equations,

x - 5 = 0, and x + 2 = 0

Rearrange and isolate the variable.

x = 5

x = -2
