I'm going to use x as the missing/unknown number here. You know that the answer is, at most, 30. You also know that a product of something means multiplication. So, something times five is, at most, 30.
This would be written as: 5x<span>≤30, as the answer is equal to 30, or less than that.
If you'd like to solve for x, you divide both sides by 5:
x</span><span>≤6
The sign does NOT flip, the number that was divided to get x alone was not a negative, so no sign-flipping is needed.</span>
That statement is an opinion.
some teachers may think they have it harder, whilst some students may think the other way.
Paul celebrated Peter's birthday, then two days later, Peter celebrated Paul's birthday. Because both Peter and Paul are males, we must use the possessive pronoun "his" when speaking of either, or in this case, both of them, which started the confusion represented in this example.
Answer:
Definition of preclude: to make impossible by necessary consequence : rule out in advance.
Explanation:
Preclude is often used in legal writing, where it usually refers to making something legally impossible. A new law may be passed by Congress to preclude any suits of a certain kind against a federal agency, for example. Some judges have found that the warnings on cigarette packs preclude any suits against the tobacco companies by lung-cancer sufferers. But there are plenty of nonlegal uses as well. Bad weather often precludes trips to the beach, and a lack of cash might preclude any beach vacation at all.
