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

Use the inequality symbols.

Explanation:

Basically, since t is at least 10,

t >= 10.

And since it is at most 22,

t <= 22.

So the final answer is: 10 <= t <= 22

Hope this helps you.

10 <= t <=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 <= t <=22

t =[10,22]

Explanation:

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

Hence, t>=10 and t<=22 -> 10<= t <=22

This can be written in interval notation as:

t =[10,22]
