No, 3 is a constant.
It can be a new variable eg x*y = xy. Or it can be a constant eg x is a variable then 3/x is another variable. x*(3/x) = 3, which is a constant.
independent variable,depedent variable and control variable are the 3 kinds of variables.
with an assignment: variable = value variable += value variable /= -3; ...
In the expression 6n+3 the variable or the unknown is n
The variable is p.
The unknown variable in the expression: 6n+3 is n
In math, isolating a variable is removing all constants from the side of the equal sign that the variable is on. ex. 3x=9 divide by 3 to isolate the variable x=3
A variable expression for the product of 6 and 3 can be written as ( 6 \times 3 ) or simply ( 18 ). If you want to introduce a variable, you could represent it as ( 6x ) where ( x ) is equal to 3. Thus, the variable expression can also be written as ( 6 \cdot 3 ) or ( 6x ) with ( x = 3 ).
There is no variable, only a fixed number.
n is the variable.
in this given variable in this is x.
In addition, the identity property means that any number or variable plus zero equals that number or variable. 3 + 0 = 3 In multiplication, the identity property means that any number or variable times one equals that number or variable. 3 x 1 = 3
