Answer:
83,333,333.3 minutes
Step-by-step explanation:
The average human breaths per minute approximately = 12 times
We have to calculate the time of breathing one billion times.
So we will divide one billion by 12.
Time taken to breath one billion times =
= 83,333,333.3 minutes
It will take 83,333,333.3 minutes to breath one billion times.
The answer is 7/3 or 2 1/3
1) You change the ÷ into x (so it will be 7/9 x 1/3)
2) You flip the 1/3 so it will be 3 ( 7/9 x 3)
3) There you have it the answer is 7/3
f(12) = 28
All you have to do is plug in 12 as x.
f(12) = 2(12) + 4
= 24 +4
= 28
And you're done! :)
