Answer:
63.4
Step-by-step explanation:
Area of arc is (pi*(11)^2*(60/360))=63.4
You would solve for x. do do that you would go in the opposite order of the order of operations.
3x-8=-2
+8 +8
3x=6
/3 /3
x=2
since it asks for what is x-6 you would just do 2-6 and your answer would be -4
Lets turn E into x and F into y.
We already know that x is 0.8. And if y/x = 0.6, we have to figure that out.
y/x = 0.6
y/0.8 = 0.6
Multiply by 8 to get y = 0.48.
So we have to find P(xy)
So if we know that x = 0.8 and y = 0.48 then all we have to do is multiply 0.48 and 0.8.
0.48 * 0.8 = 0.384
P(E and F) is 0.384.

Answer:
Step-by-step explanation:
Without a second equation relating x and y, we can solve 3x - 1/2y = 2 ONLY for x in terms of y or for y in terms of x:
x in terms of y: Multiply all three terms of 3x - 1/2y = 2 by 2, to eliminate the fraction: 6x - y = 4. Now add y to both sides to isolate 6x: 6x = 4 + y.
Last, divide both sides by 6 to isolate x:
x = (4 + y)/6
y in terms of x:
y = 6x - 4
If you want a numerical solution, please provide another equation in x and y and solve the resulting system.
