Question

pleasee HELP ME!

In the State of Florida, a redfish must be at least 18 inches long, but no more than 27 inches long for the fish to be considered a keeper. Choose the combined inequality that describes this scenario.

18 <= x <= 27

x >= 18 and x >= 27

x <= 18 or x >= 27

none of the above

Answer 1

Let's look at a similar example with different numbers. Let's say you want to express that x can be any number from 5 to 20.

To express x is greater than or equal to 5, you write x >= 5.
If you turn it all around, and write 5 <= x, which is read 5 is less than or equal to x, you have expressed the same thing.
So 5 <= x means the same as x is greater than or equal to 5.

If you want to express x is at most 20, you write x <= 20, which is read x is less than or equal to 20.

If you want to express x is at least five, but x is no more than 20, you write:
x >=5 and x<= 20, but
x>= 5 is the same as 5 <= x, so you can write it as
5 <= x and x <=20, or you can write it as a compound inequality:
5 <= x <= 20

is it the first one?
