Answer: C
Step-by-step explanation:
![50 < 5x-10\\\\60 < 5x\\\\x < 12](https://tex.z-dn.net/?f=50%20%3C%205x-10%5C%5C%5C%5C60%20%3C%205x%5C%5C%5C%5Cx%20%3C%2012)
However, the angle has to have positive measure, so:
![5x-10 > 0\\ \\ 5x > 10\\\\x > 2\\\\\therefore \boxed{2 < x < 12}](https://tex.z-dn.net/?f=5x-10%20%3E%200%5C%5C%20%5C%5C%205x%20%3E%2010%5C%5C%5C%5Cx%20%3E%202%5C%5C%5C%5C%5Ctherefore%20%5Cboxed%7B2%20%3C%20x%20%3C%2012%7D)
Answer:
4 n - 7
Step-by-step explanation:
- 3 , 1 , 5 , 9
The difference between the terms is 4, so our multiplier is 4 n
4 , 8 , 12 , 16 ( The 4 times tables )
-3 , 1 , 5 , 9 ( The original sequence )
What are we doing to get from the 4 times tables to get to the original sequence?
4 - - 3 = 7
8 - 1 = 7
12 - 5 = 7
16 - 9 = 7
We are subtracting 7 so our complete general term is 4 n -7
Answer:
B
Step-by-step explanation:
Using the rule of radicals/ exponents
×
⇔ ![\sqrt{ab}](https://tex.z-dn.net/?f=%5Csqrt%7Bab%7D)
⇔ ![\sqrt[n]{a^{m} }](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5E%7Bm%7D%20%7D)
Given
![\sqrt[3]{x^5 y}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%5E5%20y%7D)
=
× ![\sqrt[3]{y}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7By%7D)
=
→ B
If you divide 48 by 12, you will see how much a single pack costs.
48 ÷ 12 = 2
The ratio is 1 : 2 (This means every one pack costs two dollars.)
To find out how much 8 packs cost, you must multiply the number of packs by the cost of one pack.
8 x 2 = 16
Lamika will need to pay 16 dollars for 8 mors packs.
