9 people would want Red pens, and 27 would want Blue pens. You can solve this by first adding the two numbers together to get 12. Then, you would divide 48 by the 12 you just got to get 3. You can then multiply 3 and 9 by 3 to get how many of each color you need to get.

Answer:
-(√5)/3
Step-by-step explanation:
The tangent being negative means the sine and cosine have opposite signs. Using the identity ...
cos(o) = ±√(1 -sin(o)^2)
we find ...
cos(o) = -√(1 -(2/3)^2) = -√(5/9)
cos(o) = -(√5)/3
First, simplify the expression 
Here you have three terms with 
group them in the following way:
Then substitute s=-3 and t=5:
Answer: 19.
