Answer: 144°
<u>Step-by-step explanation:</u>
π(5x) = 180(4π)
x =
= 36(4)
= 144
-x - 3 < 3x + 13
+ x + x
-3 < 4x + 13
- 13 - 13
-16 < 4x
4 4
-4 < x
x > -4
The answer is C.

Step-by-step explanation:
Answer:
Small candles cost 1 dollar, large candles cost 5 dollars.
Step-by-step explanation:
Let s represent small candles, L represent large candles.
You: 15 = 5s + 2L
Friend: 21 = 6s + 3L
Now you can solve for s and L, the cost of each candle type!
15 = 5s + 2L Multiply this equation by 3 -> 45 = 15s + 6L
21 = 6s + 3L Multiply this equation by 2 -> 42 = 12s + 6L
Now we have equal L's in both equations. Use elimination to get rid of L! Subtract the equations from each other.
45 = 15s + 6L
- 42 = 12s + 6L
------------------------
3 = 3s + 0L
Now solve for s.
3 = 3s
<u>s = 1 dollar</u>
Plug s back in to get L.
15 = 5s + 2L
15 = 5(1) + 2L
15 = 5 + 2L
10 = 2L
<u>L = 5 dollars</u>
The answer is 0.1
