Question

Solve -t/5 > 15 A. t < -75 B. t > -75 C. t < -3 D. t > -3

Answer 1

For this case we must solve the following inequality:

`- \frac {t} {5}> 15`

We follow the steps below:

We multiply by 5 on both sides of the inequality:

`-t> 15 * 5\\-t> 75`

We multiply by -1 on both sides of the inequality. We must bear in mind, that when multiplying by -1, the sense of the inequality changes.

`t <-75`
