Answer: 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!
$36.4
26 times .40 is 10.4 so if you add that to 26 you get 36.4.
0.4 is rational.
Any irrational added to a rational is irrational.
Therefore we only need to add ANY irrational to 0.4 to produce an irrational number.
Examples of irrational numbers are: pi, e, sqrt(2), sin(pi/3), tan30 degrees, etc.
