-1/2
Step-by-step explanation:
First move the 2n over to the other side by subtracting it
so
4n=-8
then divide 4n by 4 and do the same to the other side
so
n= -8/4
n= -2
What is 100% of the mass ?
divide 35 by 3600
divide 38 by 60
add them together
35/3600 = 0.009722
38/60=0.6333
0.6333+0.009722 = 0.64305
so 13.64305 degrees. round answer as necssary
