1/6x = 2.....multiply both sides by the reciprocal 6/1
(6/1)(1/6)x = 2(6/1)
1x or just x = 12
        
                    
             
        
        
        
Answer:
Step-by-step explanation: 
Converte 80% into a decimal (devide it by 100) = 0.8 
Then multiply 0.8 by 1.60 = 1.28 (final result)

Answer:
Train A = 128
Train B = 68
Step-by-step explanation:
We can set up a system of equations for this problem
Let A = # of tons of Train A
Let B = # of tons of Train B
A + B = 196
A = B + 60
Now, we plug in A for the first equation, using substitution 
(B+60) + B = 196
2B + 60 = 196
Subtract 60 from both sides
2B = 136
Divide both sides by 2
B = 68
Plug in 68 for B in the 2nd equation
A = 68 + 60 
A = 128
Checking work: 128 + 68 = 196 :D hope this helped
 
        
             
        
        
        
One million: 10^6
Ten million:  10^7
So the exponent will be anywhere between 6 and 7, inclusive
