Answer:

Se usaron 700 g de queso, quedando 300 g de queso.

Step-by-step explanation:

Si se usó 1/5 más 1/2 de queso, el total usado fue:

\frac{1}{5}+\frac{1}{2}=\frac{7}{10}    

Entonces, se usó 7/10 del kg inicial de queso. Sabiendo que:

1 kg      ------ 1000 g

7/10 kg ------ x g

Entonces x = 700 g, lo que significa que se usaron 700 g de queso, quedando 300 g de queso.

Este problema se puede resolver utilizando una regla de tres, como se hizo aquí, o mefiante razones, en una equacion lineal.

Espero te haya sido de ayuda!

Anyone know how to work this out?
dsp73
The first and crucial thing we want to take notice is that the lines DF and EG intersect at point H which creates 4 different triangles in the rhombus. The innermost angles of DGH and EFH are vertical angles and vertical angles are congruent. So if the angles of the triangles are congruent than the triangles themselves are congruent. This is supported by the vertical angles theorem.
