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

In the spring, the owner of a sporting goods store decreases the price of winter gloves from $10.00 to $8.00. She increases the price of swimming goggles from $8.00 to $10.00.
Without doing the math, do you think that the percent decrease in the price of the gloves is the same as the percent increase of the goggles? Explain your reasoning.
Answer in complete sentences.
Answer:
without doing the math, we can affirm that the percent in decrease in the price of the gloves is not the same as the percent increase of the goggles. decreasing $2 from $10 will have a lower decrease than an increase of $2 from $8 since $2 represents a higher portion of $8 compared to $10

You know the total measurement of both angles is 180.
So your formula is (2x+54) + x = 180. Now rearrange to get
180 - (2x+54) = x or 180-2x+54 =x
Simply to -2x+126 = x followed by moving x and moving 126 to get
-3x = -126 , now divide both sides by -3
18)
Your complete circle is 360 and you know one angle is 90.
Set your formula to 360=90+(3x)+(x-20)+(2x-10)
Rewrite to 360 = 90+3x+x-20+2x-10 and combine like terms
360 = 90 - 20 - 10 + 3x + x+2x
360 = 60 + 6x
360 - 60 = 6x
300 = 6x
300/6 = x
50 = x

Joe's friends are going to climb a climbing wall and have invited Joe to go with them. Joe is afraid of heights and wants to know how high the climbing wall is before he climbs it. Joe is 5.5 ft tall and at 3:00 pm his shad is 2.75 ft long. At the same time, the shadow of the rock-wall is 35 ft long. How tall is the rock wall?
Answer:
Rock Wall Height = 70ft
Step-by-step explanation:
Joe's height = 5.5 ft , Joe's shadow height = 2.75 ft [At 3.30 pm]
At 3.30 pm , Joe's height : Shadow Radio = 5.5 : 2.75 = 2 : 1
So, Product real height : Shadow height = 2 : 1 [At 3.30 pm]
Rock wall shadow height = 35 ft long
As per Height : Shadow ratio = 2 : 1 . So, rock wall real height = 2 x shadow height = 2 x 35 = 70 ft long
