Answer:
x=5 y=130
Step-by-step explanation:
27x-5 and 11x-5 = 180
27x-5 + 11x-5 = 180
38x- 10= 180
38x= 190
x=5
11(5)-5 = 50
50 + y= 180
y= 130

How many solutions does have?
1/2 ( 2p + 9 ) = -p + 5
Answers
Answer:
Step-by-step explanation:
P + 4.5 = - p + 5
Bringing like terms on one side
P + p = 5 - 4.5
2p = 0.5
p = 0.5/2 = 0.25
In my opinion the answer is one solution
Answer:
1 solution.
Step-by-step explanation:
1/2(2p + 9) = -p + 5
lets solve for p
1/2 * 2p + 1/2 * 9 = -p + 5
1p + p + 9/2 = - p + p + 5
2p + 9/2 = 5
Multiply by 2 on both sides to get rid of the fraction 9/2.
4p + 9 = 10
4p = 1
p = 1/4
Therefore, there is only 1 solution.
You can now check by plugging in 1/4 for p in the original equation.

los miembros de un club social se pueden agrupar en sin que ninguno quede suelto, por parejas, por trios y por grupos de 7. ¿ cuantos miembros tiene el club, sabiendo que son mas de 80 pero menos de 90?
Answers
Answer:
El club tiene 84 miembros.
Step-by-step explanation:
El mínimo común múltiplo (mcm) es el número positivo más pequeño que es múltiplo de dos o más números. Es decir, el mínimo común múltiplo de dos números a y b es el número más pequeño que es múltiplo de a y múltiplo de b. Recordar que los múltiplos son el resultado de multiplicar un número por todos y cada uno de los números naturales.
Para calcular el mcm se descompone los números para escribirlos como un producto de números primos. Para descomponer un número se divide el número sucesivamente entre números primos hasta llegar a 1. La descomposición es el producto de las potencias de los números primos, siendo sus exponentes el número de veces que se ha dividido por dicho primo.
El mínimo común múltiplo se obtiene escogiendo todos los factores (comunes y no comunes), elevados a la máxima potencia. Es decir eliges todos los factores, pero los que se repitan serán elevados a la máxima potencia.
En este caso, los miembros de un club social se pueden agrupar, sin que ninguno quede suelto, por parejas, por tríos y por grupos de 7. Para calcular la cantidad de miembros que tiene el club, entonces debes calcular el mcm entre los números 2,3 y 7
No podemos descomponer los números como producto de primos porque ya son números primos., por lo que el mínimo común múltiplo es el producto de comunes y no comunes al mayor exponente:
mcm (2,3,7)= 2*3*7= 42
Pero sabes que los miembros son más de 80 pero menos de 90, por lo que calculas un múltiplo del mcm obtenido.
Múltiplo de 42= 2*42= 84
El club tiene 84 miembros.

Answers
Answer:
3"x4
Step-by-step explanation:
The symbol for a foot is "ft", sometimes denoted by a prime(') , also, the inch is denoted by a double prime(").
Given
2 1/2inces (2.5") blue print represents 10ft living room
We are told that the dimension of the room on the blueprint is
12'x16'
Let us convert 12' to inches
So
2.5" represents 10'
X ' will be 12'
Cross multiplying
X=(2.5*12)/10
X=3"
Let us convert 16' to inches
So
2.5" represents 10'
Y ' will be 16'
Cross multiplying
Y=(2.5*16)/10
Y=4"
the dimension of the blue print is
3"x4"

The answer is 63
Glad I could help :)
Answer:
117
Step-by-step explanation:
angle 2 is a vertical angle to 63. This means that it is equal to 2. So angle two is 63 degrees.
angle 2 and 7 add up to 180 degrees. You know that angle 2 is 63 degrees. So you do 180-63 degrees which leaves you with 117 degrees. Angle 7 is 117 degrees.
angle 5 and 7 are also vertical angles. Which means 5 is also equal to 117.
The answer is 117 degrees.
