A double inequality is an inequality where there are two signs, as opposed to one.Ex: an inequality could be 3x < 15A double inequality could be 3x < 15 < x + 20If you'd want to solve that double inequality, you split it into to expressions:3x < 15 and x + 20 > 15Then just solve.x < 5 and x > -5-5 < x < 5

In mathematics, an inequality is a statement about the relative size or order of two values.

When a quantity is subtracted or added from both sides of an inequality, the true difference in value is varied thereby changing the direction of the inequality, but when rather than subtracted or added it is multiplied or divided, it preserves the true difference in value thereby facing the same direction as the initial inequality.

Not the same as, or different from.

Less than or equal to. :)

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.

No, inequalities have more than, less then, at least, or no more than signs. Equations just have equal signs. An inequality answer can't be written as just a number it has to have a sign with it.

if there are no comparison signs (equals or inequalities, ie =, >, < etc) then it is an expression, eg "x + 5" If there is a comparison sign which is not equals, then it is an inequality, eg "x > 5"

It is still an inequality but not a new inequality. It will not alter the existence or non-existence of a solution to a system of linear equations / inequalities.

It is a statement that two numbers are NOT equal.

simply put, an expression has no "equal to" sign (=). and equation has the "equal" to sign and and inequality has either one of these signs <, >

"x3" is not an inequality. An inequality will have one of the following signs: less-than, less-than-or-equal, greater-than, greater-than-or-equal. for example: 3x - 5 < 15

yes it does

It's the same thing as solving an equation, the minor difference is to change the inequality sign when the numbers change signs(i.e negative to positive to negative).

You might mean an inequality (with 'less than', 'greater than', etc). You might mean an expression.
