Do you know what an inequality is?

anonymous · Answer

I think so

dangerousjesse · Answer

Which of these are inequalities, then?

anonymous · Answer

B?

dangerousjesse · Answer

No, B says exactly what $a+6$ equals, so it's an equation :)

anonymous · Answer

Oh

dangerousjesse · Answer

What about A, C, and D?

anonymous · Answer

Hmm.. A?

anonymous · Answer

Sorry, I suck at this, I'm just now studying this.

dangerousjesse · Answer

An inequality is when it gives you criteria your answer must match, so A is right :) Are there any other inequalities?

anonymous · Answer

I don't think so.

dangerousjesse · Answer

C is an inequality, because 4+c $must$ be greater than 1 :)

anonymous · Answer

Thanks! :)
Would you like a medal?

dangerousjesse · Answer

And an expression is like a statement, while an equation is a question. An equation asks for an answer, while an expression just states the numbers, like D. No, that's fine haha.
