Answer: A circle is 360° all the way around; therefore, if you divide an arc's degree measure by 360°, you find the fraction of the circle's circumference that the arc makes up.

3x+y+z=4<br> 2x+2y+3z=3<br> X+3y+2z=5
zhenek [66]
1) 3x+y+z=4
2) 2x+2y+3z=3
3) x+3y+2z = 5

1)*2 6x + 2y + 2z = 8
2)    2x + 2y +3z  = 3
-   __________________
       4x - z            = 5

2)*3  6x + 6y + 9z = 9
3)*2  2x + 6y + 4z = 10
-      __________________
       <span>4x+5z             =-1
</span>
4x+5z = -1
4x - z =5
- ________
6z = -6
<u>z = -1
</u><u /><u>
</u>If z=-1,

4x -(-1) =5
4x = 5-1
x = 4/4
<u>x=1</u>

3x+y+z=4
3(1)+y+(-1)=4
3+y-1=4
<u>y=2

So z=-1, x=1, y=2</u>
