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:**

None of these

**Step-by-step explanation:**

The denominators are the same, which means that you can add the numerators.

(-2x - 9) + (7x + 1) = 7x - 2x - 9 + 1 = 5x - 8

Remember to add the denominator to your answer

**(5x - 8)/(y² + 7)** is your answer

**Answer:**

(6.4, 2.2)

**Step-by-step explanation:**

(3-1)/(8-4) = 2/4 = 1/2 = m

y = mx + b

1 = 1/2(4) + b

-1 = b

y = 1/2x - 1

perpendicular slope is -2

y = mx + b

3 = -2(6) + b

15 = b

y = -2x + 15
