Question

How do you solve `-8> k/-0.4`?

Answer 1

`k>3.2`, representing real numbers greater than 3.2.

Explanation:

Multiplication of both sides of an inequality by a negative number

reverses the inequality sign. If `a> b, -a<-b`

Multiplication by `-0.4` of `-8>k/(-0.4)` turns it to

`(-8)(-0.4) < k`.

So, `k>3.2`.
