the answer to this [algebraic] expression

20 less than the quotient of a number by 5,

fifty decreased by the product of 8 and a number

This is not a single algebraic expression.

There are four separate problems to work; you need to write an expression for each of the four English phrases listed above.



When they write "a number" they're talking about some unknown number, and we don't care what it is, in this exercise. In each expression, you use a symbol (like x or n) to represent "a number".



The rest of it requires understanding the vocabulary. It seems like you might need some lessons.

Here's a quick one; links for complete lessons appear below.

English phrase: a number increased by 16

Algebraic expression: n + 16
