Answer:
There is no solution to the equation.
Step-by-step explanation:
In order to solve the system by substitution, we need to solve the second equation for x.
x - 2y = -8
x = 2y - 8
Now that we have that, we can put that in for x in the other equation and solve for y.
3x - 6y = -12
3(2y - 8) - 6y = -12
6y - 16 - 6y = -12
-16 = -12
No solution
Keep trying at this question, I believe in you! Here's the answer just in case. :)
Answer: 0.83644865915
Nearest hundredth would be 0.84.
I can explain it if you'd like.
Edit: Here's how I did it just in case anybody wants to know :) Not that anybody wants to know but just in case because you never know! :)
SOH CAH TOA
sine=opposite/hypotenuse
cosine=adjacent/hypotenuse
tangent=opposite/adjacent
So the cosine of W would be 65(the adjacent side)/97(the hypotenuse)
Because you don't know what W equals, you'd use a calculator and click the little 2nd button, then click the cos button. And then you'd type in the 65/97 and hit the equals button and that's the answer!
If I'm incorrect I guess tell me somehow? Alright, have a great day/night! ^-^

Answer:
In quadrant 1
Step-by-step explanation:
Quadrant 1 is (positive, positive) which falls in the category (10,25)
x+2=5y / 3y=12 / 2y=x+2z are essentially your equations
from the 2nd one, 3y=12, we know y=4, or in your case, circle = 4
we can then plug 4 into x+2=5y to get x+2=20, or x=18, which means diamond = 18
then, plug 4 and 18 into 2y=x+2z for 2(4)=18+2z / 8=18+2z / -10=2z / -5=z, so triangle = -5
