B and C are correct.
A circle has 360°. 2/3 of that circle is given by
2/3(360) = 720/3 = 240°.
Stu takes half of this, so his piece will have 240/2 = 120°.
He splits the remainder of it between his 2 sisters; 240-120 = 120° left; 120/2 = 60° for each sister's piece.
Answer:

Step-by-step explanation:
I am solving this using Function Notation.
We are given:

While we are to find:

In Function Notation, replace all the "
" you see with the value you are given.
So, in this case,

Would become

Now we can solve.

Use PEMDAS; Parenthesis first;

Cross divide: 1 cancels 1, -4 ÷ 2 = -2
Hence, we are left with


Therefore, the value of x is -5
Answer:
slope = - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y =
x - 2 ← is in slope- intercept form
with slope m = 
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= - 3
