Answer:
y/x, 27/9 = 3, 3 = y/27, y = 81.
Step-by-step explanation:
72 days and 10 weeks ( 10.2857 I just rounded)
Answer:
1st option
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y =
← k is the constant of variation
To find k use (3, 8 ) , that is x = 3 when y = 8 , then
8 =
( multiply both sides by 3 )
24 = k
y =
← equation of variation
Well 4/5 is 80% and 9/10 is 90%
9/10 is bigger. :)
