With is greater 5.6 or 5.06 and why

5.6 is greater because it has 6 in the 10ths column while 5.06 has 0 in the 10ths column. Obviously, 6 is greater than 0. 5.6 can also be seen as 5.60. The 0 in this number is not needed as nothing comes after it. However comparing 5.60 and 5.06 is easier as you can esily see that 5.60 is bigger. Once you get your head around it is easy. Just getting it into your head takes a bit of practise. Hopw I helped. :P

5.6 is going to be greater because when you round 5.06 it result into 5.1 so which is less than 5.6 and also 5.6 is more near to 6 so 5.6 is correct answer 

We can put in 6 - 2x for y:

2x + y = 6
2x +(6 - 2x) = 6
2x + 6 - 2x = 6
6 = 6

Since this statement is true:
x and y are all real numbers.

Hope this helps!
