Question

Answer 1

I think this is right

Answer 2

Answer:

10

Step-by-step explanation:

Let the number be x

Reciprocal = $\frac{1}{x}$

Now we are given that a non zero number is greater than 7 times its reciprocal by 9.3.what is the number.

A.T.Q.

$x-\frac{7}{x}=9.3$

$x^2-7=9.3x$

$(x-10)(x+0.7)=0$

$x=10,-0.7$

Thus the number is 10

Hence a non zero number is greater than 7 times its reciprocal by 9.3.is 10
