and for the second part b will be 3.5 because 2*3.5=7
Answer: 1/5
Step-by-step explanation:
It’s negative by the looks of it.

I hope it’s correct!
Answer:
16 hours
Step-by-step explanation:
let t be time, n the number of computers and w the number of workers, then
t =
← k is the constant of variation
To find k use the condition n = 30, w = 6 and t = 10 , then
10 =
( multiply both sides by 6 )
60 = 30k ( divide both sides by 30 )
2 = k
t =
← equation of variation
When w = 5 and n = 40 , then
t =
=
= 16 hours
