Answer:
see explanation
Step-by-step explanation:
Given that y is inversely proportional to x then the equation relating them is
y = 
← k is the constant of proportionality
To find k use the condition that y = 7, x = 9
k = yx = 7 × 9 = 63, thus
y = 
← equation of proportion
When x = 21, then
y = 
= 3
X÷2=20. Want an explanation?
220pm=10w (people*minutes)
w=22pm
14w=308pm
308pm/14p=22m
So it would take 22 minutes for 14 people to paint 14 walls.
Answer:
265.50000
Step-by-step explanation:
68.5. You take 62 and divide it by the percentage as a decimal, .905. 62 / .905 = 68.5.
