To find:
The equation for the given statement.
Solution:
Let the unknown number be x.
Half of a number : [tex]\dfrac{x}{2}[/tex]
Half of a number minus seven : [tex]\dfrac{x}{2}-7[/tex]
One and five-tenths : [tex]1\dfrac{5}{10}=1.5[/tex]
Half of a number minus seven is one and five-tenths:
[tex]\dfrac{x}{2}-7=1.5[/tex]
The required equation for the given statement is [tex]\dfrac{x}{2}-7=1.5[/tex].
Therefore, the correct option is C.
