380 / 16 = x / 6

16x = 2,280

x = 142.5

Answer is C!

(2x + 2)° =( 3x - 52)°

Since vertically opposite angles are equal.

2x - 3x = -52 -2

-x = -54

x = 54

**Answer:**

d. 4c + 11d + 15

**Step-by-step explanation:**

This is a pretty simple combining like terms problem.

10c - 6c = 4c

3 + 12 = 15

7d + 4d = 11d

Therefore, our expression will be 4c + 11d + 15.

**Answer:**

1, 2, 3

**Step-by-step explanation:**

Solve the inequality for n.

Divide both sides by 4.

4n < 16

4n/4 < 16/4

n < 4

Any number less than 4 is a solution. Now we look at the numbers in the set.

The numbers 1, 2, 3 are solutions.
