Answer:
About 1 million people live in each county.
Explanation:
Given the total population of Texas is 29.90 million people, we can round it up to 30 million.
30 million divided by 30 equals r.
r would equal about 1 million people per county.
If you wanted to get specific, 29.90 million divided by 30 equals about 996,667 people per county.
