y = 7 which you subtract from 2x which means 2 times x so you use all of those as the value of 2 to see what the answer would be after you multiply it by 2

Answer:
Option C is right
C. They are independent because, based on the probability, the first ace was replaced before drawing the second ace.
Step-by-step explanation:
Given that the  probability of drawing two aces from a standard deck is 0.0059
If first card is drawn and replaced then this probability would change.  By making draws with replacement we make each event independent of the other
Drawing ace in I draw has probability equal to 4/52, when we replace the I card again drawing age has probability equal to same 4/52
So if the two draws are defined as event A and event B,  the events are  independent
C. They are independent because, based on the probability, the first ace was replaced before drawing the second ace.
 
        
             
        
        
        
Answer:
Add 4 on both sides.
In the equation there is a -4. 
If -4+4=0, that is how you would get rid of the -4.
But, you need to add 4 to 29 to really get rid of the -4.
So, 29+4 is 33.
b=33
