thank you :) i aint trying to be mean or nothing i just nee help with my hw thank you for thw answer! :)

OpenStudy (turingtest):

You believed me? lol If you want the correct answer I will work through it with you, but posting again and again without asking for explanation will only prompt many of us to give wrong answers. I'm not being rude, I want to teach people, not give answers.

OpenStudy (anonymous):

okay i understand and can you please teach me... i didn't realize i posted it more than once my bad...

OpenStudy (turingtest):

ok then, happy to help...

OpenStudy (turingtest):

what does it mean that the fish must be at least 18 in or more? can you write that in an expression?

OpenStudy (anonymous):

are you asking me a ? or asking me to do it?

OpenStudy (turingtest):

just what does it mean? here's an example. If I say I need at least 5 apples, and I call the number of apples x, then this is\[x \ge5\](greater-than or equal-to) so this says the number of apples must be greater-than or equal-to 5. Now your problem says the fish must be at least 18in, so using what I said above, how can we write this?

OpenStudy (anonymous):

\[18 \ge x? \]

OpenStudy (anonymous):

\[18 \le 27 ?\]

OpenStudy (turingtest):

wait sorry the above is wrong

OpenStudy (anonymous):

oh..

OpenStudy (turingtest):

it should be \[x \ge18\]for the first statement

OpenStudy (turingtest):

see how this means x (the length of the fish) must be greater-than or equal to 18in? does that make sense? (sorry for not noticing immediately)
