Yes you do, you also flip the inequality sign if you multiply by a negative # The > and < signs are strictly the "Greater than" and "Less than" signs. The inequality sign is an = with a / stroke through it. If you divide an inequality by -1 it remains an inequality.
negative flip
-7b < 49Remember, when dividing or multiplying by negative numbers, the sign of the inequality is flipped.Therefore:b > -7
Almost. There's one new rule, which is that whenever you multiply or divide by a negative number, you have to flip the inequality sign. To see why, try achieving the same result without this step, using positive factors and subtraction: the equation must effectively flip itself around the sign.
you cant with the information that you gave
No, you only flip the inequality sign if you are dividing by a negative number on both sides of the inequality
You flip the inequality sign when you are dividing or multiplying both sides by a negative.You also flip the inequality sign when you "swap" the answers on both sides.The other time you flip the inequality sign is when raising both sides to a negative power. e.g. 5>4, but (5^-1)
When you divide both sides of an inequality by a negative number, the inequality sign flips.
Yes you have to flip the sign.

negative flip
Nothing, you proceed as if the < or > was an =. If you're multiplying or dividing both sides by a negative, you flip the sign. e.g. < would go to >
Only when what you're multiplying by/dividing by is negative.
Only when you multiply or divide by a negative number
When dividing by negative numbers or dividing by fractions.

For the same reason you must flip it when you multiply by a negative number. An example should suffice. 2 < 3 If you multiply by -1, without switching the sign, you get: -2 < -3, which is wrong. Actually, -2 > -3. Look at a number line if you are not sure about this - numbers to the left are less than numbers further to the right. Dividing by a negative number is the same as multiplying by the reciprocal, which in this case is also negative. These signs are strictly the "Greater than" and "Less than" signs. The inequality sign is an = with a / stroke through it. If you divide an inequality by -1 it remains an inequality.
