Otero translated the phrase "three less than a number" into the expression 3-x. Which best describes the accuracy of Otero's expression? (A.) It is accurate. The phrase can be translated as "three" = 3, "less than" = subtraction, and "a number" = x, so 3-x is the correct expression. (B.) It is inaccurate. Three is being subtracted from a number, so x-3 is what he should have written. (C.) It is inaccurate. Three is being compared to a number, so 3 < x is what he should have written. (D.) It is inaccurate. Three is being added to a number, so 3+x is what he should have written.

Option B is correct.

Step-by-step explanation:

Otero translated the phrase "three less than a number" into the expression 3 - x.

I think Otero gave a wrong expression for the phrase.

The true interpretation of the phrase is that if we assume the number as x then three less than a number means x - 3.

Therefore, Otero's expression is inaccurate. Three is being subtracted from a number, so x-3 is what he should have written. (Answer)
