Answer:
 -2.25
Step-by-step explanation:
9(1-x) = 27Y
9-9x =27y
-9x -27y = -9  multiply all terms by -1
9x +27y =9   equation (1)
x-y= -11/2 equation (2)
by solving 2 equations 
x= -3.875
y= 1.625
∴ x+ y = 1.625 +(-3.875) = -2.25
 
        
                    
             
        
        
        
corrected question:A jar contains two blue and five green marbles. A marble is drawn at random and then replaced. A second marble drawn at random. For each of the following, find the probability that: a) both marbles are blue b) both marbles are the same color  c)the marbles are different in color
Answer:
Step-by-step explanation:
<u><em>The probability was done with replacement.</em></u>
Probaility of an event happening
number of blue marbles= 2
number of green marbles=5
total number of marbles=7
(a) probability that both marbles are blue = pr(first is blue)*pr(second is blue)
                                   
                                    
(b)probability that both marbles are the same color =pr(first is blue)*pr(second is blue) + Pr(first is green)*Pr(second is green)
    
    
  
(c)Probability that the marbles are different in colors=pr(first is blue)*pr(second is green) + Pr(first is green)*Pr(second is blue)
