Answer 3

Solve an inequality exactly like you would an equation, with just ONE additional rule: if you multiply or divide by a NEGATIVE number, you flip the direction of the inequality.

Answer 4

-4x/7 > 10 (multiply by 7)
-4x > 70 (now divide by 4, keeping in mind when dividing by a negative, the sign changes)
x < - 70/4 which reduces to :
x < - 35/2

i got b

Answer 10

7x/2 < 5 (multiply by 2)
7x < 10 (divide by 7)
x < 10/7

we were not dividing/multiplying by negative, so the sign does not change
