B)150 ≥ w
C)500 ≤ w
D)150 ≤ w ≤ 500

Answer 1

The answer is D.

Hope this helps!!! :)

Answer 2

D)150 ≤ w ≤ 500

Step-by-step explanation

Let
`w` be the number of word in Kylie's essay.

We know that the essay has to have a minimum word count of 150, so the length of the essay must be greater or equal than 150 words; remember that in mathematics we say greater or equal with the sign: ≥, so we can express the statement as:

`w\geq 150`

Which is equivalent to
`150\leq w`

We also know that the essay has to have a maximum word count of 500 words, so the length of the essay must be lest or equal than 500 words; remember that we can say the same using the symbol ≤, so we can express the statement as:

`w\leq 500`

Now, we can join our tow inequalities in a compounded one:

`150\leq w\leq 500`
