Need with introduction to inequalities

need with introduction to inequalities its says circle the numbers in the replacement set that make each inequality true. with questions 1,3,5,7

< less than              ≤ less than or equal to (line underneath sign)

> greater than        ≥ greater than or equal to (line underneath sign)

# is just the number they gave you in the inequality

x < #      [you can put any number into "x", but it has to be less than #]

x > #    [you can put any number into "x", but it has to be greater than #]

x ≤ #       [number has to be less than or equal to #]

x ≥ #      [number has to be greater than or equal to #]

1. t < 7     [t is a number less than 7]

So you circle: 4, 6, 8, 0, -6

3. a ≤ -4     [a is a number less than or equal to -4]

circle: -7, -4

5.

k + 5 < 9    You can simplify this by subtracting 5 on both sides

k < 4    [k is a number less than 4]

circle: -1, 3, -2, 3.5

7. u - 5 ≥ -1  Simplify

u ≥ 4    [u is a number greater than or equal to 4]

circle: 4, 5, 4.1

because its not ur topic and its not for is for homework not that.
