Zvaries jointly as x and y. if z=3 when x=3 and y= 15, find z when x= 6 and y=9....

z=135 u × them all u mentioned

3 = k (3)(15)

3 = k (45)

3/45 = k 45/45

1/15 = k

z = (1/15)(6)(9)

z = (2/5)(9)

z = 18/5

ANSWER: z = 18/5

3 = k (3)(15)

3 = k 45

3 / 45 = k 45 / 45

1 / 15 = k

z = (1 / 15) (6) (9)

z = 18 / 5

ANSWER: z = 18 / 5

3 = k (3)(15)

3 = k 45

3/45 = k 45/45

1/15 = k

z = (1/15)(6)(9)

z = (1/15)(54)

z = 18/5

ANSWER: z = 18/5 or 3.6
