If x varies inversely with y and x = 4 when y = 9, find x when y = 6.

x = 6

given x varies inversely with y then

xy = k ← k is the constant of variation

to find k use the condition x = 4 when y = 9, hence

k = 4 × 9 = 36

x = ← inverse variation equation

when y = 6, then x = = 6

true

explanation:

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%
