$(-\infty, -1]\ or\ (25, \infty)$
$12h-3\geq15h\longrightarrow$ subtract 12h from each side $12h-3-12h\geq15h-12h\longrightarrow$ subtract $-3\geq3h\longrightarrow$ divide each side by 3 $-3\div3\geq3h\div3\longrightarrow$ divide $-1\geq h$ OR $5\gt-0.2h+10\longrightarrow$ subtract 10 from each side $5-10\gt-0.2h+10-10\longrightarrow$ subtract $-5\gt-0.2h\longrightarrow$ divide each side by -0.2; reverse the inequality sign $-5\div-0.2\lt-0.2h\div-0.2\longrightarrow$ divide $25\lt h$
