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

Answer:

The needed expression is $(\frac{p-18}{9} )$.

Step-by-step 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).

$(\frac{1}{2} ) \times p =( \frac{p}{2} )$

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

$( \frac{p}{2} ) - 9 = (\frac{p-18}{9} )$

So here, if the number is  p, then the result is :$(\frac{p-18}{9} )$

Hence, the needed expression is $(\frac{p-18}{9} )$.
