Work Step by Step

We start with the given inequality: $-\frac{r}{5}+1\geq-6$ We multiply the entire inequality by $5$ to clear the fraction: $$5\left[-\frac{r}{5}+1\geq-6\right]$$$$-r+5\geq-30$$We add $r+30$ to each side of the inequality and then combine like terms: $$-r+5+r+30\geq-30+r+30$$$$35\geq r$$We can rewrite this by flipping it around as $r\leq35$.
