Find the value of unknown if X and Y vary inversely.

x = 60, y = 12

Step-by-step explanation:

Given that x and y vary inversely then the equation relating them is

y = ← k is the constant of variation

To find k use the ordered pair (180, 3 ) , then

3 = ( multiply both sides by 180 )

540 = k

y = ← equation of variation

When y = 9, then

9 = ( multiply both sides by x )

9x = 540 ( divide both sides by 9 )

x = 60

When x = 45, then

y = = 12

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
