Sorry I cant answer it as i dont understand the question im so sorry :(
Answer:
Basketball 300
Football 100
Baseball 50
Soccer 150
Step-by-step explanation:
Half of the students would choose basketball
so 600/2 = 300
Half of the remaining students would choose soccer
so 300/2 = 150
2/3 of the remaining students would choose football
so 150 x 2/3 = 100
1/3 of the remaining students would choose baseball
150 x 1/3 = 50
Area enclosed in 
radians =$\pi r^2$
so area enclosed in $\theta$ radians=$\theta \times \frac{\pi r^2}{2\pi}= \frac{1}2\theta r^2$
does this answer your question?
Answer: c) -4
Step-by-step explanation:
Get the variables on one side of 3x+y=-2x+8 and the constants on another side:
3x+y=-2x+8
(3x+y)+2x=(-2x+8)+2x
5x+y=8
Now, multiply 5x+y=8 by -2:
-2(5x+y=8)
-10x-2y=-16
Add this equation to -3x+2y=-10:
(-10x-2y=-16)+(-3x+2y=-10)
-13x=-26
x=2
Plug x=2 into -3x+2y=-10:
-3(2)+2y=-10
-6+2y=-10
2y=-4
y=-2
Therefore, (2, -2) is the solution to the system of equations, so xy=(2)(-2)=-4
