Answer:
B
Step-by-step explanation:
Remark
If you started at W and went all the way around the circle until you wound up back at W, you will have gone 360 degrees. Since the angle measurement that prevents that is 85 degrees, the answer must be 360 - 85 = 275.
Answer:
n= -3 and n= -6
Step-by-step explanation:
![n^2 = -18 -9n](https://tex.z-dn.net/?f=n%5E2%20%3D%20-18%20-9n)
We need to solve this equation to find the value of n.
Rearranging:
![n^2 +9n +18 =0](https://tex.z-dn.net/?f=n%5E2%20%2B9n%20%2B18%20%3D0)
This is a quadratic equation and we can solve by using factorization method.
We need to make factors of 18n^2 such that their sum is equal to 9n.
So solving,
![n^2 + 9n +18 =0\\n^2 + 6n + 3n +18 =0\\n(n+6) + 3(n+6)=0\\(n+3)(n+6) =0\\=> n+3 =0 \,\, and n+6 =0\\n= -3 \,\,and \,\,n=-6](https://tex.z-dn.net/?f=n%5E2%20%2B%209n%20%2B18%20%3D0%5C%5Cn%5E2%20%2B%206n%20%2B%203n%20%2B18%20%3D0%5C%5Cn%28n%2B6%29%20%2B%203%28n%2B6%29%3D0%5C%5C%28n%2B3%29%28n%2B6%29%20%3D0%5C%5C%3D%3E%20n%2B3%20%3D0%20%5C%2C%5C%2C%20and%20n%2B6%20%3D0%5C%5Cn%3D%20-3%20%5C%2C%5C%2Cand%20%5C%2C%5C%2Cn%3D-6)
Answer:
n = -2/5
Step-by-step explanation:
n/8 - 7n/16 = 1/8
2n/16 - 7n/16 = 2/16 (making common denominators)
-5n/16 = 2/16 (Simplifying the equation)
-5n = 32/16 (Multiplying both sides by 16)
-5n = 2
n = -2/5

Answer:
(4, 26)
(-6, -24)
Step-by-step explanation:
Step 1: Substitution
5x + 6 = x² + 7x - 18
Step 2: Move everything to one side
0 = x² + 2x - 24
Step 3: Factor
(x - 4)(x + 6) = 0
Step 4: Find roots
x = 4, -6
Step 5: Plug in <em>x</em> to find <em>y</em>
y = 5(4) + 6
y = 20 + 6
y = 26
y = 5(-6) + 6
y = -30 + 6
y = -24
Answer:
