Inessa05 [86]

Answer:

La calculadora y el cuaderno costaba 9 y 1,8 euros hace tres días.

Step-by-step explanation:

A partir del enunciado podemos construir el sistema de ecuaciones lineales:

Hace tres días:

x+y = 10.80 (1)

Actualmente:

1.08\cdot x + 0.9\cdot y = 11.34 (2)

Donde:

x - Precio de la calculadora.

y - Precio del cuaderno.

Por métodos algebraicos, tenemos que el sistema de ecuaciones tiene la siguiente solución:

x = 9, y = 1.8

La calculadora y el cuaderno costaba 9 y 1,8 euros hace tres días.

*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*

♡ The Explanation/Step-By-Step ♡

- 6/100 + 5/100 + 80/100 + 9/100

Apply the fraction rule! --> a/c + b/c = a + b over c

6/100 + 5/100 + 80/100 + 9/100 = 6 + 5 + 80 + 9 over 100

Add the numbers: 6 + 5 + 80 + 9 = 100!

= 100/100 Apply the fraction rule! a/a = 1

a/a = 1 = 100/100 = 1
