The degree is 4 because it is the largest exponent out of all the variables.
I think 53.088 is the answer
The answer is 12.
Steps
If that number is x
(3+x)/(8+x)=3/4
"Cross multply"
4(3+x)=3(8+x)
12+4x=24+3x
x=12
To check: add 12 to 3 and 8. 3+12=15 and 8+12=20. 15/20=3/4
N ÷ 6 = 8
hope this helps good luck! =]
