The sum of the given expression { (w - 2.4) + (1 - 0.5w) } is 0.5w - 1.4.
<h3>What is the sum of the given expression?</h3>
Given the expression in the question;
(w - 2.4) + (1 - 0.5w)
Remove the parenthesis
w - 2.4 + 1 - 0.5w
Collect like terms and simplify
w - 2.4 + 1 - 0.5w
w - 0.5w - 2.4 + 1
1w - 0.5w - 2.4 + 1
0.5w - 1.4
Therefore, the sum of the given expression { (w - 2.4) + (1 - 0.5w) } is 0.5w - 1.4.

Answer:
<u>60 people per square mile</u>
Step-by-step explanation:
<u>Given</u> :
- Population of Mississippi = 2,844,658
- Area of Mississippi = 47,691 square miles
- Population density is the rough calculation of people (population) per square mile
<u>Population Density</u>
- Population / No. of square miles
- 2,844,658 / 47,691
- ⇒ 59.6476903 (approx.)
- ⇒ <u>60 people per square mile</u>
