If the number is represented by variable x, then twice the number is represented by 2x.
To evaluate an expression, you substitute the variable with a specified number. This process involves replacing the variable in the expression with its given value and then performing the necessary arithmetic operations to simplify the expression. For example, if you have the expression (2x + 3) and you substitute (x) with (4), you would calculate (2(4) + 3) to get (11).
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.
To replace a variable with a number, simply identify the variable in your equation or expression and substitute it with the desired numerical value. For example, if you have the expression ( x + 5 ) and you want to replace ( x ) with 3, you would write it as ( 3 + 5 ). This substitution allows you to evaluate the expression or solve an equation more easily.
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.
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).
2f
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 ).

It would be: 6/x whereas x is the unknown variable
2 would be the coeeficient the coefficient is the number before the variable
