Answer:
1st: 22, 2nd: 27, 3rd: 88
Step-by-step explanation:
Make an equation 
If she recieved x calls the 1st evening, then the 2nd evening she recieved x+5, and the 3rd evening she recieved 4x. 
x+x+5+4x=137 
Combine like terms 
6x+5=137
Subtract 5 from both sides 
6x=132
Divide by 6 on both sides 
x=22 
First: 
22 calls
Second: 
x+5
22+5
27 calls
Third: 
4x
4*22
88 calls 
Hope this helps! 
 
        
             
        
        
        
Answer:
Number of volleyballs bought = 8 
Number of basketballs bought = 11 
Step-by-step explanation:
Given that:
Total amount spent = $204.20 
Let, 
x be the number of volleyballs 
y be the number of basketballs 
According to given statement;
y = x+3     Eqn 1 
8.20x+12.60y=204.20     Eqn 2 
Putting value of y from Eqn 1 in Eqn 2 
8.20x + 12.60(x+3) = 204.20 
8.20x + 12.60x + 37.80 = 204.20 
20.80x = 204.20 - 37.80 
20.80x = 166.40 
Dividing both sides by 20.80 

Putting x=8 in Eqn 1 
y = 8+3 = 11 
Hence, 
Number of volleyballs bought = 8 
Number of basketballs bought = 11 
 
        
             
        
        
        
Answer:
V = 11
Step-by-step explanation:
All you have to do here is to multiply both sides of this equation by 13.  This will eliminate the fractions.  You'll be left with V = 11.
