How many positive integers less than 100 satisfy \[ \lvert 13-x \rvert > 85 ?\]
If the solution set to the inequality \[2\lvert{x-1}\rvert+3\lvert{x+1}\rvert < 14\] is \(\alpha < x < \beta,\) what is the value of \(10(\beta-\alpha)?\)
How many integers \(x\) satisfy \[\left|x\right| + \left|20-x\right| \le 20?\]
What is the smallest integer \(x\) that satisfies \[ |x-6| < 2x-23?\]
