Answer: He read 40% of the total time.
Step-by-step explanation:
As per given,
Total time he spent = 2 +1+2 = 5 hours
Number of hours he spent on reading = 2 hours
The percent of the total time he read = 

i.e. The percent of the total time he read = 40%
Hence, he read 40% of the total time.
No, because if you fold it where the lines are it would not be the same on both sides
Answer:
(k+2h)/(k+h)
Step-by-step explanation:
log 6 12 = (log a 12)/(log a 6) ( Log base change property)
log a 12 = log a (3*4) = log a 3 + 2*log a 2 = k+2h
log a 6 = log a (2*3) = log a 3 + log a 2 = k+h
log 6 12 = (k+2h)/(k+h)
2x+3x=5x
the +10-10 cancel each other out so it's just 80
5x+80=180
5x=180-80
5x=100
x=20
