Answer:
System 1 : {3,0};  System 2 : {6,-2}
Step-by-step explanation:
2x + 3y = 6 
-2x - y = -6 
2y = 0 
y = 0 
-2x = -6 
x = 3 
system 2 
2x + 3y = 6 
2x + 2y = 8 
y = -2 
2x -4 = 8 
2x = 12 
x = 6
 
        
             
        
        
        
The three missing lengths are the left hypotenuse, x, the middle altitude, y, and the right hypotenuse, z.
9/y = y/16
y^2 = 9 * 16
y^2 = 144
y = 12
9^2 + 12^2 = x^2
x^2 = 225
x = 15
12^2 + 16^2 = z^2
z^2 = 400
z = 20
From left to right, the sides measure 15, 12, and 20 units.
 
        
                    
             
        
        
        
16x + 21y = 555
Step-by-step explanation:
Let x be the no. of 18-hole course
And y be the no. of golf balls
16x + 21y = 555
