Yes, 5.5 is greater than g.
To find the value of g, we need to use the inequalities given. Since g>0 and g≤100, we know that g must be a whole number between 1 and 100.
The other two inequalities are not useful for finding g, so we can ignore them.
We don't know what value of g is, but we do know that 5.5 is greater than g. This means that g must be less than 5.5.
The only whole number between 1 and 100 that is less than 5.5 is 5.
So the value of g is 5, and that is the whole number you can use to unlock the door.
