Answer:
11, 13 and 15.
Step-by-step explanation:
Let's say that the odd number is "x". If x is for example 15, then the next ODD number would be 15+2=17 and the one after that would be 15+2+2=15+4=19. 
Applying that here, we get: 
Odd number* the next odd number*the next odd number=2145 
x*(x+2)*(x+4)=2145 
x*(x^2+4x+2x+8)=2145 
x^3+6x^2+8x=2145 
By solving the polynomial, you get x=11. 
Which makes our three numbers: 11, 13 and 15. 
11*13*15=2145. The answer checks.
 
        
             
        
        
        
-6/7 = -x/84
84/7 = 12
12(-6) = -72
x = -72
So, -6/7 = -72/84 because -72/84 simplifies to -6/7
        
                    
             
        
        
        
Answer:
B) 120
Step-by-step explanation:
m = miles 
 $98=$80+$0.15m
 $98-$80=$80-$80+$0.15m
 $18=$0.15m
$18/$0.15=$0.15m/$0.15
 120=m
Juliet drove 120 miles for $98.
(this is a good explanation, I guess)
