A variable is usually used for that - for example, a single letter that represents the unknown quantity.
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 write a verbal expression for (5x), you can say "five times a number" or "five multiplied by a variable." Here, (x) represents an unknown quantity, and the expression indicates that this quantity is being multiplied by 5. Alternatively, you could also phrase it as "five times x."
To write the sum of a number and thirty-seven in an algebraic expression, you would use the variable "n" to represent the number. The algebraic expression would be n + 37, where "n" represents the unknown number and 37 represents thirty-seven. This expression represents the sum of the unknown number and thirty-seven.
The algebraic expression is n + 100, where n is the unknown number.
To write the difference of ( z ) and 8 as an expression, you would subtract 8 from ( z ). This can be expressed mathematically as ( z - 8 ). This expression represents the value obtained when 8 is taken away from ( z ).
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 write a verbal expression for (5x), you can say "five times a number" or "five multiplied by a variable." Here, (x) represents an unknown quantity, and the expression indicates that this quantity is being multiplied by 5. Alternatively, you could also phrase it as "five times x."
x-15, x represents the unknown number, and to have 15 less you would simply subtract 15 from x.... therefore your answer is x-15
To write the sum of a number and thirty-seven in an algebraic expression, you would use the variable "n" to represent the number. The algebraic expression would be n + 37, where "n" represents the unknown number and 37 represents thirty-seven. This expression represents the sum of the unknown number and thirty-seven.
There is no need for a conditional expression; just write it as 10 * 100.
The algebraic expression is n + 100, where n is the unknown number.
If x is the unknown variable then it can be: x-16
s divided by 6
The variable represents either a variable amount, or an initially unknown amount. Converting a word problem to an algebraic equation requires some practice. Here is a simple example:If I earn an additional $10, I'll have $50. How much do I have now? The amount I have now is the unknown; obviously, if I add $10 to that, I'll have $50. So (omitting the dollar signs), I call this unknown amount "x" (or some other variable), and write: x + 10 = 50
To write the difference of ( z ) and 8 as an expression, you would subtract 8 from ( z ). This can be expressed mathematically as ( z - 8 ). This expression represents the value obtained when 8 is taken away from ( z ).
