Answer:
Step-by-step explanation:
1. 4x=7(x-3)      Reason: Starting equation
2. 4x=7x-21      Reason: Distributive Property
3. -3x=-21        Reason: Subtracting Combining like terms
4. x=7               Reason: Division
 
        
                    
             
        
        
        
X = sonias dvds
37 = 4x - 3
+3        +3
40 = 4x
10 = x
<span>sonia has 10 dvds</span>
        
             
        
        
        
Answer:
0.0078125
Step-by-step explanation:
If the probability of flipping a fair coin (mentally) correctly for 1 row is 0.5, then the probability of flipping it correctly for 2 rows is
0.5 * 0.5 = 0.25
for 3 rows: 0.5*0.5*0.5 = 0.125
...
For 7 rows:

 
        
             
        
        
        
180-96= 84
That means 8x+12=84
84-12=72
That means 8x=72
72÷8=9
therefore X=9
