It's C because the equations are similar
Answer: y = x + 4
Step-by-step explanation:
Since the total number of gasoline is given to be "y", with an initial quantity of filled gasoline to be "4" and the quantity of unfilled gasoline to be "x".
Therefore, the summation of the filled and unfilled quantity of gasoline will be "x + 4" which is equal to the total capacity of the tank "y".
Answer:
First option and Fourth option.
Step-by-step explanation:
To solve this exercise you need to use the following Trigonometric Identity:

In this case you know that:

Since triangle ABC is similar to triangle DEF:

Let's begin with the triangle ABC.
You can identify that:

Then, substituing values, you get:

In triangle DEF, you know that:

So, substituing values, you get:

La solución del sistema de ecuaciones es igual a (x, y) = (308/47, 42/47).
<h3>¿Cómo resolver un sistema de ecuaciones linear por igualación?</h3>
Los sistemas de ecuaciones basadas en entidades algebraicas se resuelven mediante procedimientos algebraicos. Grosso modo, el método de resolución por igualación consiste en despejar una variable en dos ecuaciones del sistema para eliminarla y reducir el número de ecuaciones <em>lineales</em> y el número de variables.
A continuación, presentamos una aplicación del método de eliminación:






y = 42/47

x = 308/47
La solución del sistema de ecuaciones es igual a (x, y) = (308/47, 42/47).

MLN is an isosceles triangle
ML = MN
3x = x + 8
Subtract x from both sides
2x = 8
Divide both sides by 2
x = 4
MN = 4 + 8 = 12
