Answer:
2n+4=n+7
Step-by-step explanation:
n=-3
Answer:
4.6
Step-by-step explanation:
Use sine rule to find the number that belongs to the box.
Thus:
![\frac{a}{sin(A)} = \frac{b}{sin(B)}](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%7D%7Bsin%28A%29%7D%20%3D%20%5Cfrac%7Bb%7D%7Bsin%28B%29%7D%20)
a = ?? (the number in the green box)
b = 5
A = 38°
B = 42°
Plug in the values
![\frac{a}{sin(38)} = \frac{5}{sin(42)}](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%7D%7Bsin%2838%29%7D%20%3D%20%5Cfrac%7B5%7D%7Bsin%2842%29%7D%20)
Multiply both sides by sin(38)
![\frac{a}{sin(38)} \times sin(38) = \frac{5}{sin(42)} \times sin(38)](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%7D%7Bsin%2838%29%7D%20%5Ctimes%20sin%2838%29%20%3D%20%5Cfrac%7B5%7D%7Bsin%2842%29%7D%20%5Ctimes%20sin%2838%29%20)
![a = \frac{5 \times sin(38)}{sin(42)}](https://tex.z-dn.net/?f=%20a%20%3D%20%5Cfrac%7B5%20%5Ctimes%20sin%2838%29%7D%7Bsin%2842%29%7D%20)

Answer:
1. A. $33 loss
2. B
Step-by-step explanation:
1. -26 - 11 - 9 +13 = -33
2. B is the only graph in which the Whole Numbers do not contain a negative or decimal (which are not WNs)
