Which inequality means that -10 is to the left of the other number on a number line?
Understand the Problem
The question asks to figure out what inequality describes the relationship where -10 is to the left of another number on a number line. This means -10 is less than the other number.
Answer
$x > -10$
Answer for screen readers
$x > -10$
Steps to Solve
- Define the variable
Let $x$ represent the other number on the number line.
- Express the relationship as an inequality
Since -10 is to the left of $x$ on the number line, this means -10 is less than $x$. We can write this as:
$$ -10 < x $$
This can also be written as:
$$ x > -10 $$
$x > -10$
More Information
The inequality $x > -10$ means that $x$ can be any number greater than -10. For example, $x$ could be -9, 0, 1, 100, or any other number that is larger than -10.
Tips
A common mistake is to write the inequality as $x < -10$. This would mean that $x$ is less than -10, which would place $x$ to the left of -10 on the number line, not to the right.
