A is greater than B (A>B). C is less than D (C<D). But what about "less than or equal"?

1000ml in a litre, so two 500ml bottles = 1litre
There would be 2 hundredths of an inch in 2 inches
2 + 200 = 202 2 + 200 = 202 2 + 200 = 202 2 + 200 = 202 Total = 808
No 1,760 yards = 1 mile 3,520 yards = 2 miles and 2 is smaller than 3,520
A system of linear inequalities
Graph the following Inequalities: x > 3
System of inequalities can be defined in mathematics as a relationship that compares 2 different values.
Two inequalities are equivalent if their solution sets are the same. For example, the inequalities 2x > 6 and 3x > 9 are both equivalent to x > 3.
-2 < 3 3 > -2
x>6 or 5<9
2+3>=or2t+9>11
Inequalities are not reflexive. Inequalities are not commutative.
-2 > -18 -18 < -2
The definition of equivalent inequalities: inequalities that have the same set of solutions
Inequalities and equations are both the same because they are both mathematical expression and they both use the same steps EXCEPT for the end. Inequalities and equations are both different because equations have an equal sign, the answer is not an interval, and the answer is a specific answer. Not a range. While inequalities don't have an equal sign, its answer is an interval, and it's answer is in a range.
