-3p > 105
divide both sides by -3 and remember that when multiplying or dividing by a negative number, you reverse the sense of the inequality:
p < -35
To check to make sure the answer makes sense, select a value of p that is less than -35. For example, -100:
(-3)(-100) > 105
300 > 105
which is true.

What inequality is greater than or equal to -5?
An inequality has no magnitude. A number can be greater than or equal to -5, but not an inequality.
What is the effect of multiplying both sides of an inequality by a negative number?
It changes the direction of the inequality.
Why it is necessary to reverse the inequality symbol when multiplying both side of an inequality by a negative number?
You need to reverse the inequality symbol when multiplying both sides of an inequality by a negative number because you are changing the sign of both sides of the equation. Since inequality, such as "less than", means "to the left of" on the number line (where left is minus and right is plus) then a number that is less than another will be greater than the other if the signs were reversed. Example: 3 is less than 4, but -3 is greater than -4.
What is a math inequality?
An inequality is when a variable and its coeefecient is greater than something. For example, 5x is greater than 2.
Solve this inequality 9h plus 2 is less than negative 79?
9h + 2 < - 79 9h < - 81 h < - 9
How do I solve this inequality y4x-5?
9
How do you solve the inequality2x -10 6?
This isn't an inequality, since there is no less-than, greater-than, less-than-or-equal, or greater-than-or-equal sign. However, solving inequalities is similar to solving equations; however, when you multiply by a negative number, you must change the direction of the inequality sign.
How do you solve an inequality with a fraction?
p+1/4 greater than and less than 2
What is the difference between inpuality and equation?
I assume you mean "inequality". An equation has an equal sign; an inequality has one of the inequality signs instead of an equal sign. These signs are: * Greater than * Greater than or equal * Less than * Less than or equal To solve an inequality, the main point to consider is that if you multiply or divide both sides by a negative number, you must invert the inequality sign. For example, if you multiply both sides by (-2), a greater-than sign would need to be changed to a less-than sign.
What happens when both sides of a less than inequality are multiplied or divided by a negative number?
The inequality sign becomes greater than (>).
Do you only flip the inequality when you divide by a negative number?
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.
How do you solve an inequality with fractions and variables on both sides?
You solve an inequality the same way you solve an equality. You add and subtract, multiply and divide, both sides by the same value in order to isolate one of the variables. The only extra thing you need to remember is that if you multiply or divide by a negative number, you must reverse the order of the inequality, i.e. less than or equal becomes greater than or equal.
What do you do with your inequality if you divide by both sides by a negative number?
If two sides of an inequality are multiplied (or divided) by a negative number, you have to invert the sign. For example, a "less-than" sign becomes a "greater-than" sign.
How do you solve an inequality in one variable?
It depends on the specific inequality. In the simplest cases, it is solved just like an equation; except that you must be careful when multiplying and dividing - if you multiply or divide both sides by a negative number, you must switch the inequality sign. For instance, a "less-than" sign would be changed to a "greater-than" sign.
What inequality is greater than or equal to -5?
An inequality has no magnitude. A number can be greater than or equal to -5, but not an inequality.
What inequality has 3 and negative 5 as two of its solutions?
x+7 is greater than or equal to 2
What is the effect of multiplying both sides of an inequality by a negative number?
It changes the direction of the inequality.
