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
