Tres hermanos van a repartirse un pastel y medio, cuanto le toco de pastel a cada uno de los hermnos

Anna71 [15]

Answer:

medio pastel cada uno

Step-by-step explanation:

Hay 3 hermanos, si decimos que un pastel entero tiene 6 pedazos entonces su fraccion seria 6/6. Si dividimos este pastel entre los tres hermanos cada uno tendria...

$\frac{6 / 3}{6}$ = $\frac{2}{6}$

Medio pastel seria la mitad de 6/6 que seria 3/6. Si dividimos esto entre los 3 hermanos cada uno tendria...

$\frac{3 / 3}{6} = \frac{1}{6}$

Ahora que dividimos los 2 pasteles tenemos que unir las fracciones para saber cuanto pastel le toco a cada hermano...

$\frac{2}{6} + \frac{1}{6} = \frac{3}{6}$ o medio pastel cada uno

PLEASE HELP!!!!!!!! IMAGE ATTACHED!!!!

erma4kov [3.2K]

Answer:

Step-by-step explanation:

4) (-2,3) ; (-1,-2)

$Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{-2-3}{-1-[-2]}\\\\=\frac{-5}{-1+2}\\\\=\frac{-5}{1}\\\\=-5$

5) line is parallel to x-axis. So, slope= 0

6) (1,1) ; (-2, -1)

$Slope=\frac{-1-1}{-2-1}\\\\=\frac{-2}{-3}\\\\=\frac{2}{3}$
