You do 3/5 minus 3/5 which cancels out to 0. Then you do 6 minus 4 which is 2. The answer is 2.
3*60 = 180 minutes
80/180 = 0.44
1-0.44 = 0.56
it was a 56% decrease in commute time
Hej!
You would need to multiply both sides by -1
Resulting in...
y=2x-5
Set up an algebraic equation. This is what it looks like based on what the question tells you:
Let a = area of pentagon
a+27 = 4a-15
3a-15 = 27
3a = 42
a = 14
