If z = 4.0 and y = 9.6, what is the value of x?
krok68 [10]

Answer:

The value of x will be "1.4".

Explanation:

The given values are:

y = 9.6

z = 4.0

As we know,

The relation between x, y and z is:

⇒ z = \frac{y}{x}

and,

⇒ x=\frac{y}{z}

On substituting the given values, we get

⇒    =\frac{5.6}{4.0}

⇒    =1.4
