An algebraic expression can have a mixture of numbers and variables, but it does not contain an equals sign.
A variable expression for 5 divided by r would be 5/r. In algebra, when a number is divided by a variable, it is represented as the number (in this case, 5) divided by the variable (r). This expression shows the quotient of 5 and r, where r can be any real number except 0 to avoid division by zero error.

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
To write an expression that represents the sum of a number and 12, you can use a variable to represent the unknown number. For example, if you let the variable ( x ) represent the number, the expression would be ( x + 12 ). This indicates that you are adding 12 to whatever value ( x ) holds.
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).
To write the quotient of a number and 6 as an expression, you can represent the number as a variable, such as ( x ). The expression would then be written as ( \frac{x}{6} ). This indicates that the number ( x ) is being divided by 6.
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 for 5 divided by r would be 5/r. In algebra, when a number is divided by a variable, it is represented as the number (in this case, 5) divided by the variable (r). This expression shows the quotient of 5 and r, where r can be any real number except 0 to avoid division by zero error.

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