8.5t-2.9t>28
Subtract 2.9t from both sides.
5.6t>28
Combine 8.5t and -2.9t to get 5.6t.
t>\frac{28}{5.6}
Divide both sides by 5.6. Since 5.6 is positive, the inequality direction remains the same.
t>\frac{280}{56}
Expand \frac{28}{5.6} by multiplying both numerator and the denominator by 10.
t>5
Divide 280 by 56 to get 5.
