13

Answer 1

Answer:

13<x-21

(No correct option, unless the last option is incomplete and would be 13<x-21)

Step-by-step explanation:

The sentence is:

13 is less than x minus 21

We need to know that some expressions are related to some symbols to make equations:

"is less than" is the symbol "<", and

"minus" is the symbol "-".

So, writting the expression as an inequation (it's an inequation because of the symbol "<"), we have:

13 < x - 21

So there is no correct answer, unless the last option is incomplete (if the last option is not just 13, and is 13<x-21, that would be the correct option)
