Answer:
Equation shown 
Step-by-step explanation:
Eq(1): x-3y=-12
 X=-12+3y
 =-4+y
Eq(2): x-3y=-6
 X=-6+3y
 =-2+y
 
        
                    
             
        
        
        
Answer:
12.53 miles
Step-by-step explanation:
6² + 11² = x²
36 + 121 = x²
157 = x²
x = 12.53 miles
 
        
                    
             
        
        
        
In one full rotation/revolution, a point on the edge travels a distance equal to the circumference of the gyroscope, or 2<em>π</em> (18 cm) = 36<em>π</em> cm. Convert the angular speed, 36<em>π</em> cm/rev, to linear speed:
(36<em>π</em> cm/rev) • (35 rev/min) = 1260<em>π</em> cm/min ≈ 3958 cm/min
