well, xy=k, so
12*6 = k
If y varies inversely as x, and y = 12 when x = 6, what is K, the variation constant?

y=k/x
y=12,x=6
12=k/6
k=12*6
k=72
y=12,x=6
12=k/6
k=12*6
k=72
y varies inversely as x. y=12 when x=7. Find y when x=6.
If all men had identical body types, their weight would vary directly as the cube of their height. The tallest person reached a record height of 8 feet 11 inches (107 inches) before his death at age 22. If a man who is 6 feet 10 inches tall (82 inches) with the same body type as the tallest person weighs 190 pounds, what was the tallest person's weight shortly before his death?
