-5 x 10

Answer 6

do i keep the signs the same and not change them?

Answer 7

\[-5 < x < 10\]

Yes.

The only real thing you need to remember for inequalities is that if you ever multiply the inequality by -1 (or just any negative number), it changes the direction of the sides.

Answer 8

B.

For example:

\[2 < -x < 3\]
I multiply by -1
\[-2 > x > -3\]
