Which of the following statements are true of literal equations? (mofre than 1 answer)

They consist primarily of variables.

They are often called formulas.

They mostly use words.

They often describe real-world relationships.

They are hardly ever used.

The literal equations are those which made use primarily of variables to represent known values. These equations allow the use of variables instead of the true distance, time, slope, interest, etc. With literal equations, we are often asked for the value of one of the variables in terms of the other. Hence, the answer to this item is the first and the second one.

The correct answers are:

They consist primarily of variables.

They are often called formulas.

They often describe real-world relationships.

Explanation:

Literal equations are defined as "equations in more than 1 variable whose variables represent specific quantities."

This means that literal equations consist mostly of variables.

Since the variables represent specific quantities, this means they typically represent real-life situations.

Since they represent real-life situations, these equations are often formulas for things in the real world (such as area, volume, perimeter, circumference, etc.)
