1.235%
Step-by-step explanation:
Paso 1
Calculamos el costo de envío
= $ 1620 - $ 1600
= $ 20
Paso 2
¿Cuál es el porcentaje de mi compra que me cobraron por los gastos de envío?
Esto se calcula como:
(Costo de envío / Cargos totales) × 100
= 20/1620 × 100
= 1.2345679012%
= Aproximadamente = 1.235%

Step-by-step explanation:
Answer:
x=-2.25,y=-2.25
Step-by-step explanation:
The given system is
![4x - y = - 9 \\ 3x - 3y = 0](https://tex.z-dn.net/?f=4x%20-%20y%20%3D%20%20-%209%20%5C%5C%203x%20-%203y%20%3D%200)
We want to solve the system for x and y that makes the system true.
Let us multiply the first equation by 3 while maintaining the second equation:
![12x -3 y = - 27 \\ 3x - 3y = 0](https://tex.z-dn.net/?f=12x%20-3%20y%20%3D%20%20-%2027%20%5C%5C%203x%20-%203y%20%3D%200)
Subtract the current second equation from the first one.
![12x = - 27](https://tex.z-dn.net/?f=12x%20%3D%20%20-%2027)
Divide through by 12:
![x = - \frac{27}{12} = - 2.25](https://tex.z-dn.net/?f=x%20%3D%20%20-%20%20%5Cfrac%7B27%7D%7B12%7D%20%20%3D%20%20-%202.25)
From the second equation we have:
![3x = 3y](https://tex.z-dn.net/?f=3x%20%3D%203y)
This implies that:
![x = y = - 2.25](https://tex.z-dn.net/?f=x%20%3D%20y%20%3D%20%20-%202.25)
