An algebraic expression can have a mixture of numbers and variables, but it does not contain an equals sign.
4xz=16
If x is used to represent the unknown number, then the expression for 20 times a number would be 20x.
You have to assign some variable name to "a number", for example, "n". The difference would be: 20 - n Half this difference is: (1/2) (20 - n) Or alternately: (20 - n) / 2

If the number is represented by variable x, then twice the number is represented by 2x.
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
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).
2 would be the coeeficient the coefficient is the number before the variable
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.
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
4xz=16
The coefficient would be the number multiplied by the variable, in this case: 7
In the context of algebra, "4d" would typically be considered a numerical expression rather than a variable. A variable is typically a letter or symbol that represents an unknown quantity that can vary, while a numerical expression is a combination of numbers and mathematical operations. In this case, "4d" represents the product of the number 4 and the variable "d," making it a numerical expression.
Because it varies, otherwise it would be a constant.
