Answer:
17pi/15
Step-by-step explanation:
s = r *theta where r is the radius and theta is the central angle in radians
Convert 51 to radians
51 * pi/180 = 51pi/180
s = 4 * 51pi/180
    = 17pi/15
 
        
                    
             
        
        
        
10x + 2y - 6 = 0
Multiply 5x + y - 3 = 0 by 2
2(5x + y - 3 = 0) = 10x + 2y - 6 = 0
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
Remark
Anything multiplied by 0 = 0. So the whole right side is 0.
(6x - 9)*3 - 1  = 0                       Add 1 to both sides.
(6x - 9)*3 - 1 + 1 = 0 + 1             Combine
(6x - 9)*3 = 1                             Divide both sides by 3
(6x - 9)*3/3 = 1/3                      Simplify
(6x - 9) = 1/3                             Remove brackets. Add 9 to both sides
6x - 9+9 = 9 1/3                        Combine
6x = 9 1/3
6x = 28/3                                   Divide both sides by 6
6x / 6 = 28/3 // 6                       Invert the 6 and multiply.
x = 28/3 * 1/6
x = 28/18 
Answer
x = 14/9
