The algebraic expression is n + 100, where n is the unknown number.
n/84q
To write "25 less than a number" as an algebraic expression, you would represent the unknown number as a variable, such as "x." Therefore, the algebraic expression would be written as "x - 25." This expression indicates that you are subtracting 25 from the unknown number represented by "x."
2(25-15)=2 x 10=20
k-2.5 An algebraic expression is just using variables (in this case, k) for unknown numbers. Since the question is asking what the number k minus 2.5 is, your answer is k-2.5.
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
There is no need for a conditional expression; just write it as 10 * 100.
If x is the unknown variable then it can be: x-16
The algebraic expression is n + 100, where n is the unknown number.
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
n*5 - 6
