Math Writing Inequities

When we multiply or divide an inequality by a negative we ____________.

• keep the inequality symbol the same

• reverse the inequality symbol

• make it equal only

• make it less than only

Solve:     5( 6 + 3r) + 7 ≥ 127

• r ≤ 6

• r ≥ 6

• r ≤ -6

• r ≥ -6

-4x + 14 ≤ 54

• x ≥ - 10

• x ≤ -10

• x ≥ 10

• x ≤ 10

10 < 3x + 19

• x < 3

• x > 3

• x < -3

• x > -3
