Just for an example, lets say you'd have to solve 35 ÷ 7.
First, the first number always goes inside the┌ (I'll call it "the house") The first number, of course, is 35 in this case.
Second, the second number goes on the outside of "the house" on the left. Of course, the 7 is the second number in this case.
Third, now that you've set up the problem, now you can solve it!
Compare the number on the outside of the house to the first digit on the inside of the house. In this case, that's 7 and 3. Since 7 doesn't go into 3, you move on to the next number that's inside the house, 5. In other words, now you're comparing 7 to 35.
7 goes into 35 5 times, so now you'd put a 5 on top of the house above the 5 in 35!
35 ÷ 7 = 5!

<u>Answer:</u>
<u>Explanation:</u>
<em>Factors are numbers that if they are divided, then they would be divisible. We can see that the term is multiplied with 3 terms. Hence, they are definitely factors of that term. However, there is one more factor that is divisible by 2xy. The number 1 is divisible by 2xy. Hence, the factors of this term is 2, x, y, and 1.</em>
Hoped this helped.

Answer:
93.75 feet and 187.5 feet
Step-by-step explanation:
Let the width of the rectangular area be x feet and the length be y feet. A farmer with 750 feet of fencing wants to enclose a rectangular area and then divide it into three pens with fencing parallel to one side of the rectangle. So, there will be 4 widths and 2 lengths, thus
![4x+2y=750\\ \\2x+y=375\\ \\y=375-2x](https://tex.z-dn.net/?f=4x%2B2y%3D750%5C%5C%20%5C%5C2x%2By%3D375%5C%5C%20%5C%5Cy%3D375-2x)
Find the area:
![A(x)=x\cdot y=x\cdot (375-2x)=375x-2x^2](https://tex.z-dn.net/?f=A%28x%29%3Dx%5Ccdot%20y%3Dx%5Ccdot%20%28375-2x%29%3D375x-2x%5E2)
Find the derivative:
![A'(x)=375-2\cdot 2x=375-4x](https://tex.z-dn.net/?f=A%27%28x%29%3D375-2%5Ccdot%202x%3D375-4x)
Equate it to 0:
![375-4x=0\\ \\4x=375\\ \\x=93.75\ feet\\ \\y=375-2\cdot 93.75=187.5\ feet](https://tex.z-dn.net/?f=375-4x%3D0%5C%5C%20%5C%5C4x%3D375%5C%5C%20%5C%5Cx%3D93.75%5C%20feet%5C%5C%20%5C%5Cy%3D375-2%5Ccdot%2093.75%3D187.5%5C%20feet)

Answer: total books = 8k
Step-by-step explanation:
k = books on each shelf
total books = bookcases * shelves per bookcase * books per shelf (k)
total books = 1 * 8 * k
total books = 8k
