It would be 8.185 since there aren't 2 numbers that evenly go into 67
        
                    
             
        
        
        
Step 1: -3(x+2y=3)
Step 2: -3x-6y=-9
Step 3: 3x cancels out with -3x
Step 4: add 2y and -2y, and add 3 and 5 
Step 5: the answer is NO SOLUTION or INFINITE SOLUTION
        
             
        
        
        
Answer:
50
Step-by-step explanation:
 
        
                    
             
        
        
        
You can solve this using trigonometric functions.
The angle between the fish and the ground is
tan θ = 100 / 50
θ = tan-1 (2)
θ = 63.43°
The height of the bird before it dropped the fish is already given, which is 100 yards.
        
             
        
        
        
Find area of lumber 2 x 10 = 20
garage needs 324 feet, rec room needs 430, bonus room needs 283
324 + 430 + 283 = 1037
1037/20= 51.85 feet of lumber
hope this helps
