Suppose y varies jointly as x and z. If y=15 when x=1/2 and z=6, what is the constant of variation?

k = 5

Step-by-step explanation:

Given y varies jointly as x and z then the equation relating them is

y = kxz ← k is the constant of variation

To find k use the condition y = 15 when x = and z = 6 , then

15 = k × × 6 = 3k ( divide both sides by 3 )

5 = k

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

sorry i need the points
