Can you post better picture, I can barely read the answer choices
(7u+4v)(7u-4v)
49u+28uv+28uv
49u+56uv
Answer:
7/16
Step-by-step explanation:
1 3/4 = 7/4
(7/4) / 4 = 7/4 * 1/4
7/16
I am unfortunately not too sure about this, I have not heard of a proportional equation before even after getting my degree, because an equation usually isn't proportional, only expressions are and there are usually 2 terms.
Here's my best attempt. The first equation isn't proportional since y is inversely proportional to the 7 in the denominator. The second is proportional, and the k constant is 10.
I cannot provide any further explanations.
Let me know if this was helpful!
Answer: 35.6 (choice A)
To get this answer, add up the values: 39+42+27+45+25 = 178
Next, divide that result by 5 because there are 5 scores added up in the previous step. Doing this division gets us to: 178/5 = 35.6
