The value of p when x = 21 is p = 32/3 .
Given :
we know that ,
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form p * x = k or p = k / x
we know that
For p = 14, x = 16
Find the value of k
k = p * x
substitute the values
k = 14 * 16
= 224
so
The equation is equal to
p = 224 / x
if x = 21
substitute the value of x in the equation
p = 224 / 21
Divide by 7 both numerator and denominator
p = 32 / 3
