How do you solve and write the following in interval notation: t is at least 10 and at most 22?

Sep 2, 2017

Use the inequality symbols.

Explanation:

Basically, since t is at least 10,

t $\ge$ 10.

And since it is at most 22,

t $\le$ 22.

So the final answer is: 10 $\le$ t $\le$ 22

Hope this helps you.

$10 \le t \le 22$

Explanation:

'At least $10$', means that $t$ can be equal to $10$ or is more than $10$.

'At most $22$' means that $t$ can be equal to $22$, but can also be less than $22$.

This gives the lower limit and the upper limit to the interval.

$10 \le t \le 22$

$t = \left[10 , 22\right]$

Explanation:

We are told that $t$ is at least 10 and at most 22.

Hence, $t \ge 10 \mathmr{and} t \le 22 \to 10 \le t \le 22$

This can be written in interval notation as:

$t = \left[10 , 22\right]$
