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)

Answer: The answer is 21360
Step-by-step explanation:
Answer:
The answer to your question is letter c and d.
Step-by-step explanation:
A. 15 × 9 = 135 and 135 – 75 = 60 This answer is not correct because it is not necessary to multiply the # members by the cost of each tree, the answer is incorrect.
B. 3 × 15 = 45 and 45 + 15 = 60 This answer is incorrect because it's using a number 3 that is not part of the data.
C. 45 ÷ 9 = 5 and 5 × 15 = 75
. This answer is correct, first finds the number of tree bought by each member and after that multiply it by the cost of each tree.
D. 45 × 15 = 675 and 675 ÷ 9 = 75 This answer is correct, first found the total cost and after divide it by the number of members.
