Simplified expression:

Step-by-step explanation:

Let be "x" the sea level.

We know that the highest point of the country is 5,762 feet about the sea. Then, we can write the following expression:

Since the lowest point is 9 feet below sea level, we can write this expression:

The difference is the result of a subtraction. Therefore, we can find the expression that represent the difference between the elevations by subtracting   and  :

The expression simplified is:

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
