Write an inequality.

Eight fewer than a number is at least 20.

Let's represent the number as 'x'.

The inequality for the given problem is:
x - 8 ≥ 20

Let's start by defining the number as "x".

"Eight fewer than a number" can be written as "x - 8".

The inequality "is at least 20" can be written as "≥ 20".

Combining these, the inequality becomes:

x - 8 ≥ 20

To write an inequality based on the given information, let's break it down.

We are given that "Eight fewer than a number." Let's represent the number with the variable 'x'.
The phrase "Eight fewer than a number" can be expressed as x - 8.

Next, we have "is at least 20." The phrase "is at least" indicates that we want a value that is greater than or equal to the given value.
So, we can write this as x - 8 ≥ 20.

Therefore, the inequality representing the given information is:
x - 8 ≥ 20.
