Yes. A variable by itself, or anything that contains a variable, would be a variable expression (unless the variable cancels out, as in "x - x", which always has the same value).

It would be: 6/x whereas x is the unknown variable

Assuming you call your number "n", the expression would be "14n". You can replace "n" with whatever variable you want to use.

The coefficient would be the number multiplied by the variable, in this case: 7

Because it varies, otherwise it would be a constant.

Twice a number can be represented as 2x, where x is the unknown number. Adding 27 to this expression gives 2x + 27. Therefore, "twice a number plus 27" can be written as the algebraic expression 2x + 27.

An algebraic expression can have a mixture of numbers and variables, but it does not contain an equals sign.

it is the number you would use to solve the problem

The corresponding expression would be 2x - 6 = 4.

If the number is 'z', then five less than twice the number is ( 2z - 5 ).

Let the number be x and so the expression is 4x -3

A variable expression is an expression which contains variables(symbol that represents a certain value). For example, 4a-90. 4a-90 would be the expression an a is a variable
