Question

if z is inversely proptional to x and z=5 when x=7, find the value of x when z=70

Answer 1

Answer:

1/2

Step-by-step explanation:

$z \: = \: \frac{k}{x}$

As Z is inversely proportional to x, where K is constant

• For Z = 5 and X = 7 K =?

Thus K = 35

• Now for Z = 70 K = 35 X = ?

Thus X = 35/70

x = 1/2
