if z varies jointly as x and y and z=6when x=10 and y=8.find k or the constant variation?​

Sagot :

Answer:

k = 3/40

Step-by-step explanation:

(1) Write the equation

z = kxy

(2) Substitute the value for x, y, z in the equation

6 = k(10)(8)

(3) Multiply and simplify the right side of the equation

6 = 80k

(4) Divide both sides by 80 so that only k will remain in one side of the equation.

k = 6/80

(5) Simplify

k = 3/40
