What is a expression for 3 fewer than 18
as in like a-b stuff bc i forgot ☠

Answer 1

18-3

Explanation:

The required expression is 18-3 (The given phrase is '3 fewer than 18')

We need to find the algebraic expressions for the given phrase.

Algebraic expressions:

The algebraic expressions for the phrase "a fewer than b" is:

b - a

Similarly, the algebraic expressions for the phrase "3 fewer than 18" is:

18 - 3 (18 being b and 3 being a)

This means that our expression is 18 - 3 because that's the only way this is possible. You can add other things (like complicate it/ turn it into a 'find a' algebra question or a linear equation, I gave an example below- not the best i know but its like 1 am and I can't lol) like:

Find x: 18 - x = 16

x = 16

Answer 2

18-3

It should be 18-3 since that's the only way to write it as an expression. If you want to add a variable, the answer would be something like x=18-3 or x+3=18, which is not an expression..

Explanation:

It asks for an expression for 3 fewer than 18. Since it is an expression, you should not include any equal signs, thus the only possible answer would be 18-3.
