Your rate of change is 3/2.. It will always be the coefficient of 'x'
True this is because of the number of angles a quadrilateral has which is 4
X+6y=12
6y=12-x
y=12/6- x/6
y=(-1/6)(x)+2
To figure this out you can do a proportion
34 X
---- = ------
55 100
Then you would cross multiply to get
55x=3400
Next you would divide 3400/55 which would come out to be 61.8181818 which would be your percentage 61.81%
Answer:
Step-by-step explanation:
you would multiply by 3 on both sides to get the division to go away.
then subtract 8 from both sides.
then you have your answer
