1. add 40 to the 40 and 25
2. now you have
3. then you have
4. then square root
5.then round answer to nearest tenth which is
You would keep the 2 hour for the whole number of the mixed number and then, make the minutes (15) as a fraction with 60, and divide them both by 20. that is just for the mixed number.
you first plug (substitute) in y
-3x - 3(-5x-17)=3
then distribute
-3x+15x+51=3
now combine like terms
12x+51=3
subtract to get 12x by itself
12x=3-51 or 12x=-48
lastly divide by 12 to find x
12x/12=-48/12
x=-4
now find y by plugging x into the other equation
y=-5(-4)-17
y=3
(-4,3)
Convert to hours, then days, then years
60 minutes per hour
1000000/60=50000/3=16666.7 hours
24 hours per day
16666.7/24=694.4 days
365 days per year
694.4/365=1.9
the average person lives at least 1.9 years
maybe, I guess
