Answer 1

`8y\text{ + 21 }\ge20`

Step-by-step explanation

We need to translate the sentence into an inequality.

The sentence given is:

The sum of a number times 8 and 21 is at least 20

Using variable y to represent the number:

* The sum of a number times 8 and 21 means:

y * 8 + 21

=> 8y + 21

* is at least 20 means that it is greater than or equal to 20

Therefore, the inequality is:

`8y\text{ + 21 }\ge20`
