Answer:
$421.30
Yearly Componded Interest
$250 * 19% = $47.50 = $297.50 <-- Year One Balance
$297.50 * 19% = $56.53 = $354.03 <-- Year Two Balance  
$354.03 * 19% = $67.27 = $421.30 <-- Year Three Balance  
 
        
                    
             
        
        
        
Answer:
first is -3, second number is 0
Step-by-step explanation:
you have two equations x+3=y and 4*x+12=5*y
Use the first one and write y in terms of x in the second equation:
4*x+12=5*(x+3)
4*x+12=5*x+15
12=5*x-4*x+15
12=x+15
x=-3
 
        
             
        
        
        
Answer:
x = 3
Step-by-step explanation:
3(x - 4) = -3
Divide by 3
3/3(x - 4) = -3/3
x-4 = -1
Add 4 to each side
x-4+4 = -1+4
x = 3
