Question

Can someone help me with 23,24, and25 please there a little confusing

Answer 1

Explanation:

`23)\\\\-14\leq(x)/(10)\qquad\text{multiply both sides by 10}\\\\(10)(-14)\leq10\!\!\!\!\!\diagup^1\cdot(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}\\\\(6v)/(6)\geq(-54)/(6)\\\\v\geq-9`
