Question

Choose the best definition for the following term: variable (1 point)

A letter that holds the place for some unknown value in mathematics

A process where you must look for terms that have identical variable parts and then combine their coefficients

A process where if two things are equal, one can be put in the place of the other and nothing will change

Terms that have identical variable parts

Answer 1

A variable is a letter that stands for a missing variable. "A" would be the best answer. It is not a process, and they aren't necessarily a term.

I hope this helps!
