Is a variable a variable expression?
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).
How would 6 divided by a number be written in an algebraic expression?
It would be: 6/x whereas x is the unknown variable
What is the algebraic expression for the product of 14 times a number?
Assuming you call your number "n", the expression would be "14n". You can replace "n" with whatever variable you want to use.
What is the coefficent in this algebraic expression 7d plus 2?
The coefficient would be the number multiplied by the variable, in this case: 7
Why do you think a variable in an expression is called a variable?
Because it varies, otherwise it would be a constant.
What would the variable expression be for double a number f?
2f
What is twice a number plus 27 in an algebraic expression?
Let's call "a number" x. Twice that number would be 2x, and then add 27, so the expression would be 2x + 27.
Does a variable expression consists only of numbers?
An algebraic expression can have a mixture of numbers and variables, but it does not contain an equals sign.
What does the variable represent in an addition or subtraction expression?
it is the number you would use to solve the problem
What is the algebraic expression for 6 less than twice a number is 4?
The corresponding expression would be 2x - 6 = 4.
Is a variable a variable expression?
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).
How would you represent using z as the variable represent five less than twice a number?
If the number is 'z', then five less than twice the number is ( 2z - 5 ).
What is the coefficient of X in the expression 2x + 10y?
2 would be the coeeficient the coefficient is the number before the variable
How would 6 divided by a number be written in an algebraic expression?
It would be: 6/x whereas x is the unknown variable
What is the algebraic expression for the product of 14 times a number?
Assuming you call your number "n", the expression would be "14n". You can replace "n" with whatever variable you want to use.
Which expression represents 3 less than four times a?
Let the number be x and so the expression is 4x -3
What does varable expression mean?
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
