a. n is < or equal to -2
b. n is > or equal to-2
C. n is < or equal to -6
d. n is > or equal to -6

Answer 1

C.

Explanation:

`- 5n - 10 > 20`

add 10 to both side

so...

`- 5n > 30`

divide by -5 so, the sign flips because multiplying or dividing with a negative number changes the sign.

30/5=6
