Ask questions in the comment section if you have questions. I'm happy to help! <3

Step-by-step explanation:

What the question is telling you is that x and y and proportional, almost like a ratio.

<h2>x : y</h2><h2>-3 : 6</h2>

Now we have to find y when x is four.

<h2>-3 : 6</h2><h3>     to </h3><h2> 4 : y</h2><h2 />

Let's create a proportional equation...

<h3>(-3 / 6) = 4 / y</h3><h3>- 1 / 2 = 4 / y</h3>

What can we divide by four to create -1/2?

<h2>y = -8.</h2>

Geometry help please
natta225 [31]
You know angles B and C are both 60°, the values of the angles in an equilateral triangle. Since the sum of angles in a quadrilateral is 360°, you have
B + C + x + y = 360°
60° +60° + x + y = 360°
x + y = 240°
