If the number is represented by variable x, then twice the number is represented by 2x.
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.
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.
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.
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).
If the number is 'z', then five less than twice the number is ( 2z - 5 ).
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.
Let the number be x and so the expression is 4x -3
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.
