Let
x------> the number of multiple choice question
y------> the number of free response question
we know that
 -----> equation A
 -----> equation A

 -----> equation B
 -----> equation B
Substitute equation B in equation A
![3[15-y]+8y=55](https://tex.z-dn.net/?f=3%5B15-y%5D%2B8y%3D55) 
 
 
 
 
 
 
 
 
 
Find the value of x


therefore
<u>the answer is</u>
the number of multiple choice question are 
the number of free response question are 
 
        
                    
             
        
        
        
Surface area of cylinder is given by area of circle + area of the rectangle that curved around the cylinder
Area of the base of the cylinder = 

Area of the cylinder 'wall' = width × length = 

×

=

×

=

Note that the wall of the cylinder is in the shape of a rectangle. The width of the rectangle is the height of the cylinder. The length of the rectangle is the circumference of the circle base.
Surface area of cone is given by 

 where 

 is the slanted height of the cone
SA of cone = 

Hence total painted surface area is 
 
 
        
        
        
The sum of the interior triangles in a triangle is 180, so if we add all the angle measures together, we should get 180. Therefore, we can make an equation like this,

Simplify this.



Now we can find each angle measure.











So the angle labeled  is the largest angle in the triangle.
 is the largest angle in the triangle.
 
        
                    
             
        
        
        
(f∘g)(x) is equivalent to f(g(x)). We solve this problem just as we solve f(x). But since it asks us to find out f(g(x)), in f(x), each time we encounter x, we replace it with g(x).
In the above problem, f(x)=x+3.
Therefore, f(g(x))=g(x)+3.
⇒(f∘g)(x)=2x−7+3
⇒(f∘g)(x)=2x−4
Basically, write the g(x) equation where you see the x in the f(x) equation.
f∘g(x)=(g(x))+3 Replace g(x) with the equation
f∘g(x)=(2x−7)+3
f∘g(x)=2x−7+3 we just took away the parentheses
f∘g(x)=2x−4 Because the −7+3=4
This is it
g∘f(x) would be the other way around
g∘f(x)=2(x+3)−7
now you have to multiply what is inside parentheses by 2 because thats whats directly in front of them.
g∘f(x)=2x+6−7
Next, +6−7=−1
g∘f(x)=2x−1
Its a lts easier than you think! 
Hope this helped
