I'm hoping I'm right but I think it's c. 10.0
turn it into a fraction for example (i know i am making it harder than it seems with variables) x:y you turn it into then you take the top number in the fraction and put it in the "house"
y ⟌x
-hope this helps

Answer:
x=2.5, y=-5. (2.5, -5).
Step-by-step explanation:
5y+2(2.5)=-10
5y+5=-10
5y=-10-5
5y=-15
y=-15/5
y=-5

If you were trying to get the area of a whole circle, you would use
Area = pi r^2
You have to modify the formula to show that just part of the circle has an area that you are interested in.
The new formula is
Area = (theta/360) pi r^2
Givens
r = 30 cm
theta = 100
Solution
Area = (100 / 360) * pi * r^2 Substitute the givens into this formula
Area = (5 / 18) * pi * 3^2 Expand
Area = (5 / 18) * pi * 9 Cancel 9 into 18
Area = 5/2 * pi
Area = 2.5 * pi
