Answer:
The needed expression is [tex](\frac{p-18}{9} )[/tex].
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).
[tex](\frac{1}{2} ) \times p =( \frac{p}{2} )[/tex]
Now, subtracting 9 from the result above, we get:
[tex]( \frac{p}{2} ) - 9 = (\frac{p-18}{9} )[/tex]
So here, if the number is p, then the result is :[tex](\frac{p-18}{9} )[/tex]
Hence, the needed expression is [tex](\frac{p-18}{9} )[/tex].
