1) solving
we get ![8.5a+38](https://tex.z-dn.net/?f=8.5a%2B38)
2) Solving
we get ![-2+h](https://tex.z-dn.net/?f=-2%2Bh)
Step-by-step explanation:
Rewrite each algebraic expression with fewer terms
![1) 9.5(a + 4)-a](https://tex.z-dn.net/?f=1%29%209.5%28a%20%2B%204%29-a)
Solving:
Multiplying 9.5 with terms inside the bracket
![9.5(a + 4)-a\\=9.5a+38-a\\=8.5a+38](https://tex.z-dn.net/?f=9.5%28a%20%2B%204%29-a%5C%5C%3D9.5a%2B38-a%5C%5C%3D8.5a%2B38)
So, solving
we get ![8.5a+38](https://tex.z-dn.net/?f=8.5a%2B38)
![8 + h- 2\times 5](https://tex.z-dn.net/?f=8%20%2B%20h-%202%5Ctimes%205)
Solving:
![8 + h- 2\times 5\\=8+h-10\\Combining\,\,like\,\,terms:\\=8-10+h\\=-2+h](https://tex.z-dn.net/?f=8%20%2B%20h-%202%5Ctimes%205%5C%5C%3D8%2Bh-10%5C%5CCombining%5C%2C%5C%2Clike%5C%2C%5C%2Cterms%3A%5C%5C%3D8-10%2Bh%5C%5C%3D-2%2Bh)
So, Solving
we get ![-2+h](https://tex.z-dn.net/?f=-2%2Bh)

A few tips:
- If the numbers are in negatives, the greatest number should be the closest from 0.
- If the numbers are in positives, the greatest number should be farthest from 0
- If the numbers are in positives and negatives, the number which is farthest from 0 will be the greatest.
Solution (Verification for Option A):
<u>In this case, all the numbers are in negatives.</u>
- => -3 > -4 > -7 > -8 > -9 (Correct)
Solution (Verification for Option B):
<u>In this case, a few numbers are in positives and in negatives.</u>
- => 9 > 7 > 6 > -5 > 4 (Incorrect)
Solution (Verification for Option C):
<u>In this case, a few numbers are in positives and in negatives.</u>
- => 8 > -6 > 5 > -4 > 1 (Incorrect)
Solution (Verification for Option D):
<u>In this case, a few numbers are in positives and in negatives.</u>
- => -3 > -1 > 0 > 2 > 7 (Incorrect)
