A constant that multiplies a variable is no longer a constant. By its very definition, a constant is something that can never be different. The result of variable multiplication is thus a variable, not a constant.
I would say that the above answer is not necessarily true. The common equation for the area of a circle is: area = pi * r2
The fact that you are multiplying the mathematical constant pi by a variable does not change the value of pi.
Agree with the second answer. Jsut to add, a constant that multplies a variable is called a coefficient.
Static properties are those which do not change, and variable properties are those which can fluctuate. For example, with respect to electrical service to a home, a static property of this could be described as the voltage being provided to the property (which should remain constant), and a variable property could be described as the cost for the service (which fluctuates with the market).
Variable names should show what data the variable holds so others reading your code will understand it. For example, a variable holding the age of a user should be called "age" or "user_age", or something similar.

Substituting environment variable valuesTo enable the substitution of variable values at the command line or in scripts, enclose the variable name in percent signs (that is, %variablename%). By using percent signs, you ensure that Cmd.exe references the variable values instead of making a literal comparison. After you define variable values for a variable name, enclose the variable name in percent signs. Cmd.exe searches for all instances of the variable name and replaces it with the defined variable value. For example, if you create a script that contains different values (for example, user names) and you want to define the USERNAME environment variable for each user with these values, you can write one script using the variable USERNAME enclosed in percent signs. When you run this script, Cmd.exe replaces %USERNAME% with the variable values, which eliminates the need to perform this task manually for each user. Variable substitution is not recursive. Cmd.exe checks variables once. For more information about variable substitution, see For and CallFrom the above Technet description, the % signs are used to ensure that "cmd.exe" does not literally use the term "systemroot" and references the systemroot variable correctly (So therefore %systemroot% is recognised correctly as the C:\ drive, if C:\ is your systemroot).
Depends on the programming language you are using. I will give two simple examples. In Command Prompt and when creating a batch file, you declare a variable by entering the "set" command. You can use different switches to change the type of variable you are declaring. /p makes the variable able to accept user input. /a makes the variable a numerical expression. In Python, you declare a variable just by stating the name of the variable and its value. x = value.
A coefficient is a number that multiplies a variable.
It is the coefficient of the unknown variable.
The number that multiplies a variable in an algebraic expression is called a coefficient. It is the numerical factor that is multiplied by the variable to form a term in the expression.

A constant. * * * * * The expected answer is more likely to be "coefficient".
The constant is the number; the variable is the letter.
The question is about an oxymoronic expression. A constant cannot be a variable and a variable cannot be a constant!
