27.5
22= K(8)
Divide 8 on both sides to get your K value 
2.75 = K 
Plug your K value into the other equation
Y= 2.75(10)
Solve to get Y
Y= 27.5
When the problem asks "vary directly", it is saying that you are multiplying your K value with your X value(K*X). If the problem is asks "vary indirectly", it is saying that you are dividing your K value by your X value (K/X)

Answer:
A, B, C
Step-by-step explanation:
Assuming the choices are:
A. 
B. 
C. A+
D. 
Put simply, a polynomial in this case will be a function that has at least one variable raised to a power greater than 1.
Choice A already has a variable raised to a power greater than 1 ( ), so no additional manipulation is needed.
), so no additional manipulation is needed.
Choice B also has a term that is already raised to a power greater than 1 ( ). It is the same for choice C (
). It is the same for choice C ( ).
).
Choice D does not have an obvious variable raised to a power greater than 1. When the equation is manipulated it becomes  . Since -1 is less than 1, choice D is not a polynomial.
. Since -1 is less than 1, choice D is not a polynomial.
 
        
                    
             
        
        
        
45 / 0.12 = 375
