The only like terms are the x+2x so we add them to get the simplfied answer
 
        
                    
             
        
        
        
Well if you multiply 66.7 x 100 you get 6,670.0. When multiplying by numbers like 10, 100, 1,000, etc, just simply transfer the 0's. So in this case, there are 2 0's in 100, so you add 2 of the 0's behind 66.7.  So when you add the 2 of the 0's you get 6,670.0 which should be your answer.

The ratio of x and 2=x:2
not greater than is <
So I'd say the answer would be x:2<14
