Eight less than four times a number is less than 56. what are the possible values of that number?
ox> 12
x < 12
x < 16
ox> 16

For this case we can algebraically rewrite the expression given as:

Where:

x: Represents the unknown number

Subtracting 8 from both sides of the inequality we have:

Dividing between 4 on both sides of the inequality:

We multiply by -1 on both sides taking into account that the sense of inequality changes:

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
