Given:
X varies directly as the product of u and v, and inversely as their sum.
Mathematically, this can be written as:
X = k(uv) / (u+v), where k is the constant of variation.
Given that x = 3 when u = 3:
3 = k(3*3) / (3+3)
3 = 9k / 6
18 = 9k
k = 2
Now we need to find the value of x when u = 3 and v = 3:
X = 2(3*3) / (3+3)
X = 18 / 6
X = 3
Therefore, the value of x when u = 3 and v = 3 is 3.
X varies directly as the product of u and v and inversely as their sum .if x=3 when u=3 what is the value of x ,if u=3 and v=3
