Explanation:
Prepositions are words used to connect other words within a sentence and express the relationship between them. Depending on what type of relationship they express, prepositions can be prepositions of time, place, direction, agent, possession, and so on.
Examples of prepositions found in the sentences are<em> from, under, in, </em>and <em>at.</em>
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>
(Fake but if your using it for a essay just use it) I was waiting for my uncle to get home, from the army we haven’t seen him in forever. Well I thought to myself he will be proud of me 11 next week. As next week approached we got ready finally the day I thought to myself. As my mom picked me up from school I was kind of sad I won’t be able to see him for the next 3 years. I walked into the door everyone screamed surprise... even my uncle was there that day.
