1. i have never been good with that stuff i do apologize but i do have answers for 2 and 3
2. 36
3. 6<span />
Do you mean 47/10?
Because 10 divided by 47 is 0.212765957
First you distribute making it 4y-24=0
second you isolate the variable making it 4y=24
finally you divide by four giving you the answer of y=6
450 is 75% of 600 you can find this by divding 450 by 0.75
Answer:
The answer is A. [-4/3]
For the second part the answer is a rotation 90 CCW about origin
Hope this helped!
