What equations? Explanation:
I pretty sure you would use x over 38.00 = 20 over 100 then cross multiply them
So first of all you need to plug in the x=8 into both equations which will make the first equation be equals to 44 than plug in the x into the second equation and you will get 4 over -1 so in my opinion it should be b=44
Step-by-step explanation:
12,000 views = 4 hours
=> 30,000 views = 4 * (30000/12000) = 10 hours.
Hence it will take 10 hours.
