-6x + 18 = 7- (4x + 9) help will give brainlyist
andreyandreev [35.5K]

Answer:

X = -5

Step-by-step explanation:

-6x + 18 = 7 - (4x + 9)

first we simplify the parentheses.

distribute the invisible number one created by the negative sign in front of the parentheses to get -6x + 18 = 7 - 4x - 9

then simplify further by subtracting 9 from the right side, leaving you with

-6x + 18 = -2 - 4x

next, add 2 to both sides to isolate the variable.

-6x + 20 = -4x

then, to isolate the variable further add 6x to both sides.

20 = -4x

divide both sides by -4 to isolate the variable

-5 = x

so, x = -5

First, in order to find the length of side w, you must first find the angle W. 
A triangle must be 180 degrees in total. 93 + 37 makes the triangle only have 130 at the moment. 
180 - 130 = 50
So angle W is 50 degrees
Now using this, we can use law of sines.
\frac{w}{sin50} =  \frac{31}{sin37}
Now multiply sin 50 on both sides. It can be written like so:
\frac{31sin50}{sin37}
Now plug this in a calculator. 
Answer is 39.5
