Answer
t $\geq$ 12
Work Step by Step
$\frac{3}{4}$t - 4 $\geq$ 5
Add 4 to both sides to get $\frac{3}{4}$t by itself:
$\frac{3}{4}$t - 4 + 4 $\geq$ 5 + 4
$\frac{3}{4}$t $\geq$ 9
Now, multiply both sides by $\frac{4}{3}$ to get t by itself:
($\frac{4}{3}$)($\frac{3}{4}$)t $\geq$ 9 ($\frac{4}{3}$)
t $\geq$ 11.99 $\approx$ 12
