Answer:
There are 45 library books in the classroom.
Step-by-step explanation:
The problem says that Marvin, Latoya and Abdulla each read 3/7 of the library books in the classroom. If Latoya read 3/7 of the books, we can form a proportion to determine the number of total library books in the classroom.
To solve for 'x', we can either cross-multiply and divide, or we can multiply the denominator by the same factor as the numerator to get a product of 15. In this case, the same factor would be 5, so 7 x 5 = 35. If we cross-multiply:
3x = (15)(7) or x = 35.
12
Step-by-step explanation:
Quotient rule,
Do this,
a^(n-3)=a^9
Since the exponents have to be the same, this turned into a simple one step equation:
n-3=9
+3 +3
**n = 12, so the final answer is 12.
Answer:
Ratio is : 5/4 or 5 : 4
Step-by-step explanation:
The ratio of the number of stories in the first building to the number of stories in the second building :
60 : 48 or 60/48
Both numbers have 3 and 4 as common factors. So
3 * 4 * 5 : 3 * 4 * 4
5 : 4 is the ratio in the simplest terms striking of the common factors.
Y= -2x/5 + 11/5

Answer:
Step-by-step explanation:
![8x + c = k\\\\8x + c-c = k -c \ \ \ \ \ \ \ \ \ [\ subtract \ c \ from \ both \ sides \ ]\\\\8x = k - c\\\\\frac{8x}{8} = \frac{k-c}{8} \ \ \ \ \ [ \ divide \ both \ sides\ by\ 8 \ ]\\\\x = \frac{k-c}{8}](https://tex.z-dn.net/?f=8x%20%2B%20c%20%3D%20k%5C%5C%5C%5C8x%20%2B%20c-c%20%3D%20k%20-c%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5B%5C%20subtract%20%5C%20c%20%5C%20from%20%5C%20both%20%5C%20sides%20%5C%20%5D%5C%5C%5C%5C8x%20%3D%20k%20-%20c%5C%5C%5C%5C%5Cfrac%7B8x%7D%7B8%7D%20%3D%20%5Cfrac%7Bk-c%7D%7B8%7D%20%5C%20%5C%20%5C%20%5C%20%5C%20%5B%20%5C%20divide%20%5C%20both%20%5C%20sides%5C%20%20by%5C%20%208%20%5C%20%5D%5C%5C%5C%5Cx%20%3D%20%5Cfrac%7Bk-c%7D%7B8%7D)
