Hi!
Change 719.711 to 720 and 8.75 is 9.
and 720 dividided by 9 is 80
Change 719.711 to 700 and 8.75 to 9.
700 divided by 9 is 77.77...
those are the only two I can think of that'll work, but I think that 80 would be the best answer.
Let's assume it takes x hours.
People will be inversely related to hours, which makes more sense, sorry for my previous wrong answer.
Calculate the relationship: k = 10*4 = 40
So, 8x = 40, x = 5
Answer:
8
Step-by-step explanation:
The value of X must be 0. Hope this helps and a Brainliest would be appreciated
