Answer:
d The length of each petal is 4, and the number of petals is 4.
Step-by-step explanation:
 
        
             
        
        
        
You said  X = (5y+1) / (y-2)
Multiply each side by (y-2): 
X(y-2) = (5y+1)
Eliminate parentheses:
Xy - 2X = 5y + 1
Add  2X  to each side:
Xy = 5y + 1 + 2X
Subtract  5y  from each side:
(X-5)y = 1 + 2X
Divide each side by  (X-5):
<em>y = (1+2X) / (X-5)  </em>
 
        
                    
             
        
        
        
Step-by-step explanation:
0.5 ( r + 2.75 ) = 3
r + 2.75 = 3 / 0.5
r + 2.75 = 6
r = 6 - 2.75
r = 3.25
 
        
                    
             
        
        
        
The answer is 3x. 
Factor out 3x and u get 3x(x-3).
        
             
        
        
        
117/7 already is in the simplest form. It can be written as 16.714286 in decimal form (rounded to 6 decimal places).
