Which is greater? 79.47mi,54.28mi,65.5mi,98.43mi

The greater value of the  given set is 98.43.

Explanation:

Here the units of the distance given for all the data is miles(mi).

So, the greater value is that value which has higher magnitude.

Values are 79.47,54.28,65.5 and 98.43

Values in their increasing order is given by

             54.28 < 65.5 < 79.47 < 98.43

 Values in their decreasing order is given by

             98.43 > 79.47 > 65.5 > 54.28

So, the greater value of the  given set is 98.43.

the solution is 12x-6y
