Question

Write an expression with the same meaning as " the result of multiplying 1/2 by a number, then subtracting 9". Please help

Answer 1

The needed expression is
`((p-18)/(9) )`.

Explanation:

Here the given expression is :

"the result of multiplying 1/2 by a number, then subtracting 9"

Let us assume the given number is p.

Firstly we multiply the given number p with (1/2).

`((1)/(2) ) * p =( (p)/(2) )`

Now, subtracting 9 from the result above, we get:

`( (p)/(2) )  - 9 = ((p-18)/(9) )`

So here, if the number is p, then the result is :
`((p-18)/(9) )`

Hence, the needed expression is
`((p-18)/(9) )`.
