Answer
Write an expression for the number of pencils Maggie gives to jamil.
To prove
Let us assume that the number of pencils Katie have = x
As given
Katie gives Maggie half of her pencils.
[tex]Katie\ gives\ Maggie\ half\ of\ her\ pencils = \frac{1x}{2}[/tex]
As given
Maggie keeps 5 and gives the rest to jamil.
Thus
[tex]Number\ of\ pencils\ Maggie\ gives\ to\ jamil = \frac{1x}{2} - 5[/tex]
Therefore the expression for the number of pencils Maggie gives to jamil are [tex]\frac{1x}{2} - 5[/tex].
