Answer:
I am pretty sure you can set up a proportion.
12 games is the answer 
Step-by-step explanation:
8                  X
_        *         __
30                45
8*45=30x
360=30x
x=12
 
        
             
        
        
        
Answer:

Step-by-step explanation:

Expand the brackets.

Add -9x and 5x

Add 4x and 6x on both sides.

Add the like terms.

Divide 12 into both sides.


 
        
                    
             
        
        
        
70 you solve by making a proportion 2.8/x =4/100
        
             
        
        
        
I'm going to assume that the room is a rectangle.
The area of a rectangle is A = lw, where l=length of the rectangle and w=width of the rectangle. 
You're given that the length, l = (x+5)ft and the width, w = (x+4)ft. You're also told that the area, A = 600 sq. ft. Plug these values into the equation for the area of a rectangle and FOIL to multiply the two factors:

Now subtract 600 from both sides to get a quadratic equation that's equal to zero. That way you can factor the quadratic to find the roots/solutions of your equation. One of the solutions is the value of x that you would use to find the dimensions of the room:

Now you know that x could be -29 or 20. For dimensions, the value of x must give you a positive value for length and width. That means x can only be 20. Plugging x=20 into your equations for the length and width, you get:
Length = x + 5 = 20 + 5 = 25 ft.
Width = x + 4 = 20 + 4 = 24 ft.
The dimensions of your room are 25ft (length) by 24ft (width).
