Step-by-step explanation:
[tex]23)\\\\-14\leq\dfrac{x}{10}\qquad\text{multiply both sides by 10}\\\\(10)(-14)\leq10\!\!\!\!\!\diagup^1\cdot\dfrac{x}{10\!\!\!\!\!\diagup_1}\\\\-140\leq x\to x\geq-140\\\\24)\\-20<k-11\qquad\text{add 11 to both sides}\\\\-20+11<k-11+11\\\\-9<k\to k>-9\\\\25)\\-6v\leq54\qquad\text{change the signs}\\\\6v\geq-54\qquad\text{divide both sides by 6}\\\\\dfrac{6v}{6}\geq\dfrac{-54}{6}\\\\v\geq-9[/tex]
