I'm assuming you mean independent and dependent variables? They are usually expressed as something like y=f(x) where the variable y is dependent on the value of the x.
Two times a variable means multiplying the variable by 2. For example, if the variable is represented as ( x ), then 2 times the variable is expressed as ( 2x ). This represents a value that is twice whatever the variable's value is.
Neither 100 nor 16.6 is a variable of any kind.
Not always. It could be a constant. For example x is one variable, and y = x-2 is another variable. Then x - y = x - (x-2) = 2.
The independent variable, because it isn't affected by the other factors.
A numerical constant.
what are the two kinds of variable
It is the kind of variable that you purposely change.
It is a qualitative variable.

If a variable has possible values -2 6 and 17 then this variable is an Integer.
the y variable always changes and x is constant
Yes it can, but it depends on what kind of variable and how it relates to the whole number.
A constant expression.
