Queremos encontrar y resolver una ecuación algebraica para encontrar el <u>número de vecinos de la casa de Rosa.</u>

La solución es: La casa de Rosa tiene 84 vecinos.

<em>La información que se nos da es:</em>

  • 2/7 de el número total de vecinos son rubios.
  • La cuarta parte de estos, es decir: (1/4)*(2/7) del número total, tiene ojos azules.
  • Sabemos que hay 6 vecinos con ojos azules.

Si definimos a N como el número total de vecinos, tendremos que:

(1/4)*(1/7)*N = 6

Ahora solo debemos resolver esto para N, para ello multiplicamos por 4 y por 7 en ambos lados:

4*7*(1/4)*(2/7)*N = 4*7*6

2*N = 168

Ahora dividimos por 2 ambos lados:

2*N/2 = N = 168/2 = 84

<u>La casa de Rosa tiene </u><u>84</u><u> vecinos.</u>

The endpoints of RS are R(–5, 12) and S(4, –6). What are the coordinates of point T, which divides RS into a 4:5 ratio?
Ksivusya [100]

Answer:

Option 2 is correct that is (-1,4)

Step-by-step explanation:

We will use the section formula to find the coordinates of T

Formula is (x,y)=\frac{m_1x_2+m_2x_1}{m_1+m_2},\frac{m_1y_2+m_2y_1}{m_1+m_2}

Here, m_1=4,m_2=5,x_1=-5,y_1=12,x_2=4,y_2=-6

On substituting the values in the formula we get

(x,y)=\frac{4\cdot 4+5\cdot -5}{4+5},\frac{4\cdot -6+5\cdot 12}{4+5}

\Rightarrow (x,y)=\frac{4\cdot 4+5\cdot -5}{4+5},\frac{4\cdot -6+5\cdot 12}{4+5}

\Rightarrow (x,y)=\frac{16-25}{9},\frac{-24+60}{9}

\Rightarrow (x,y)=\frac{-9}{9},\frac{36}{9}

\Rightarrow (x,y)=(-1,4)

Therefore, option 2 is correct that is (-1,4)
