The answer is b=3 for your problem
Answer:
x = 4
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 the condition y = 8 when x = 10
k = yx = 8 × 10 = 80
y = 
← equation of variation
When y = 4, then
4 = ( multiply both sides by x )
4x = 80 ( divide both sides by 4 )
x = 20

Lila selecting black = 7/12 (7 black ribbons out of 12 ribbons total)
Jessica *then* selecting a green ribbon = 5/11 ( 5 green ribbons left out of 11 ribbons left)
Chance of this specific event = (7/12)*(5/11) = 35/132</span>Mike <span>· 6 years ago</span>
