is this correct? 19 - 8 < 12 would the number 8 make this number sentence true?

Yes it would make it true. It is saying 19 - 8 is less than 12. So then you can simply do the math, and you come out with 11 is less than 12. Which is a true statement.

19 - 8 < 12
11 < 12

To check if the number 8 would make the number sentence true, let's substitute 8 for the variable on the left side of the inequality and see if the resulting statement is correct.

Substituting 8 in for the variable, the inequality becomes:
19 - 8 < 12

Evaluating this expression:
19 - 8 = 11

Now we have:
11 < 12

Since 11 is less than 12, the statement is true. Therefore, the number 8 does make the number sentence true.

Yes. You're right. :-)
