Answer:

A) En 19 paquetes habrá 152 velitas.

B) Se podrían armar 40 paquetes iguales con 320 velitas.

Step-by-step explanation:

La regla de tres simple directa consiste en una relación de cantidades con proporcionalidad directa, que se da cuando dadas dos cantidades correspondientes son magnitudes directamente proporcionales. Esto es, si al multiplicar o dividir una de ellas por un número, la otra queda multiplicada o dividida por ese número.

La regla de tres simple permite hallar un cuarto término de una proporción conociendo los otros tres.

Siendo a, b y c datos conocidos y x la incógnita, la regla de tres simple se aplica de la siguiente manera:

a ⇒ b

c ⇒ x

Entonces: x=\frac{c*b}{a}

A) En este caso la regla de tres simple se aplica de la siguiente manera: si en 3 paquetes hay 24 velitas, en 19 paquetes ¿Cuántas velitas habrá?

3 paquetes → 24 velitas

19 paquetes → x

Entonces x=\frac{19 paquetes*24 velitas}{3 paquetes}

x= 152 velitas

<u><em>En 19 paquetes habrá 152 velitas.</em></u>

B) En este caso la regla de tres simple se aplica de la siguiente manera: si hay 24 velitas en 3 paquetes, hay 320 velitas ¿Cuántos paquetes se podrán armar?

24 velitas → 3 paquetes

320 velitas → x

Entonces x=\frac{320 velitas*3 paquetes}{24 velitas}

x= 40 paquetes

<u><em>Se podrían armar 40 paquetes iguales con 320 velitas.</em></u>

A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the translation?
DedPeter [7]

Answer:

C

Step-by-step explanation:

Any time you move up or down, it affects the "y" coordinate, and going up is positive so 5 units up is y + 5.

Moving left or right affects the "x" coordinate and moving left is negative so

x - 3

(x - 3, y + 5)

 Hence, C is the correct answer
