Question

A county has the following rule for voting:

"Citizens under the age of 18 are not allowed to vote."

Part A: Write an inequality to show the age of citizens who are allowed to vote. (5 points)

Part B: Describe in words how you can show the solution to this inequality on a number line. (5 points)

Answer 1

Citizens under the age of 18 are not allowed to vote. This means that 18 is included within the ones that can vote.

let x = the citizens under the age of 18

x < 18 is your inequality (Part A)

For the solution, because it does not include 18, you'll use an open dot (a non-filled in circle) placed on 18, and going to the left (less than).


hope this helps
