Answer:
8 ejercicios
Step-by-step explanation:
De acuerdo a la información dada, puedes plantear las siguientes ecuaciones:
x+y= 45 (1)
7x-1y= 19 (2)
x= ejercicios que resolvió bien
y= ejercicios que resolvió mal
Primero, puedes despejar x en (1):
x= 45-y (3)
Segundo, debes reemplazar (3) en (2):
7(45-y)-1y=19
315-7y-1y= 19
315-8y= 19
315-19= 8y
296= 8y
y= 296/8
y= 37
Tercero, debes reemplazar el valor de y en (3) para encontrar x:
x= 45-37
x= 8
De acuerdo a esto, la respuesta es que el hijo ha resuelto bien 8 ejercicios.
Answer:
I am assuming you want to know how many total cartons will be used which is about 61 cartons with a remainder of 10 eggs.
Step-by-step explanation:
To solve for this problem we have to divide 742 by 12:
742/12 = 61.833333...
This means that the "whole" number of cartons will be 61
If you want to find the remaining eggs not in decimal form, you have to mulitlpy 12 by 61 and take this number away from 742 to find the remainder:
**Note: 12 * 61 can also be written as 61 * 12
12 * 61 = 732 → 742 - 732 = 10 eggs
I hope this helps!
