You would just do 5.7-8.1, which is -3.6 degrees Celcius. Hope I helped!
When the son is 8, the father is five times that so 8*5 = 40, difference between their ages is 32
twice as old 32*2 = 64
The father will be 64.
(4logs/2hours) = (x logs/8 hours)
(4/2) = x/8)
Cross multiplication gets you:
(4)(8) = (2)x
32 = 2x
x = 16
16 logs
the correct answer is 83.
yyyyyeeeeeeaaaahhhhhh bbbbooooiii
