Patricio compro 3 cañas de pescar en $548,84 y 3 ansuelos en $55,86 <br> Cuanto recivi de buelto
Whitepunk [10]

Mediante el uso de inecuaciones y con el desconocimiento de la cantidad pagada, Patricio recibirá vuelto si y solo si pagó una cantidad <em>mayor</em> que $ 604,47.

<h3>¿Cómo determinar el vuelto por concepto de una compra?</h3>

En esta pregunta tenemos el caso de una persona que compró tres cañas de pesca y tres anzuelos, de los cuales debemos determinar el vuelto recibido por el comprador.

Para recibir vuelto es preciso que el comprador una cantidad de dinero mayor al total de compra, que es la suma de los subtotales por producto, a su vez producto del número de elementos comprados y su precio unitario.

Puesto que no conocemos la cantidad entregada por el comprador, solo podemos concluir mediante la siguiente inecuación:

p > $ 548,84 + $ 55,86

p > $ 604,47

Mediante el uso de inecuaciones y con el desconocimiento de la cantidad pagada, Patricio recibirá vuelto si y solo si pagó una cantidad <em>mayor</em> que $ 604,47.

If the length of a rectangular yard is represented by w+4 and the width by 2w+5, write a simplified expression in terms of w tha
adell [148]

Answer:

P = 6w + 18

Step-by-step explanation:

A rectangle is a plane shape having a LENGTH and a WIDTH.

Length (l) = w + 4

Width (w) = 2w + 5

To write a simplified equation in terms of w to represent the total length, let's used the idea of a PERIMETER of a RECTANGLE.

Perimeter (P) = 2 ( l + b)

Where l = length= w + 4

Where b = width = 2w + 5

P = 2( w + 4 + 2w + 5)

P = 2( 3w + 9)

P = 6w + 18
