Let's first define variables.
y: number of shares of $ 10
x: number of shares of $ 12
We write the system of equations:
10x + 12y = 210
y = 2x + 5
Solving the system:
x = 75/17
y = 235/17
Answer:
she has:
75/17 shares of $ 12
235/17 shares of $ 10
<span>Point A with coordinates (x,y) rotated 180 degrees around O gives point A' with coordinates (-x,-y).
Hope this helps :D

Answer: All Real Numbers Are Solutions
9/20 because if you count the red and blue out of the 20, theres 9. So you have a 9/20 chance it will hit red or blue.
24. (2x+2)+(2x+2)+(2x+2)=(x+8)+(x+8)+(x+8)+(x+8)
6x+6=4x+32
-6 -6
6x=4x+26
-4x -4x
2x/2=26/2
x=13
