Answer:
I believe it is -0.6
Step-by-step explanation:
subtract 8,5 by 13,2 and you should get (-0.6)

We have the following system:
![\begin{cases}4x-2y&=8\\2x+y&=2\end{cases}](https://tex.z-dn.net/?f=%5Cbegin%7Bcases%7D4x-2y%26%3D8%5C%5C2x%2By%26%3D2%5Cend%7Bcases%7D)
Here, a simple solution to find the answer is to graph the two lines and see how many times they intersect.
I've attached a graph, with
in red and the other equation in blue.
See that the lines only intersect once, at
. This means the system only has one solution.
This question, at first, may seem quite confusing. However, this problem can be simplified by just analyzing the triangle with "y" in it.
It is given that one angle of the triangle is 48 degrees. The other interior angle must be 90 degrees since the angle adjacent to that is a right angle, and supplementary angles add up to 180 degrees.
Thus, we have a triangle with angles of 90 degrees, 48 degrees, and y degrees. These must all add up to 180 because this is a triangle.
![y+90+48=180](https://tex.z-dn.net/?f=y%2B90%2B48%3D180)
Subtract both sides by 90 and 48
![y=42](https://tex.z-dn.net/?f=y%3D42)
Hope this helps and have an awesome day! :)
174% is the answer, just multiply the whole thing by 2/2 considering percentages are a fraction of 100
Answer:
I think it's 12+3x
but idk it's been a long time
