The equation formed using the given data is 195 = x + 12 and your final score is 183 points.
How to form an equation?
Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say your final score is x
Given that,
Your final score x is 12 points less than your friend's final score.
So,
x = friend final score - 12
Now,
Friend final score = 195
So,
x = 195 - 12
x + 12 = 195
195 = x + 12
Now,
x = 195 - 12 = 183
Hence "The equation formed using the given data is 195 = x + 12 and your final score is 183 points".

Answer:
I believe it would be curved due to the circular structure.
Step-by-step explanation:
Your answer is going to be B.
You would add 3 on both sides
3x - 3 + 3 = 13 + 3
3x = 16
Sum of all the angles in Quadrilateral is equal to 360
so, 360 = 80+110+75+x
x = 360-265
x = 95
