Hello.
All we should do in order to evaluate the given expression is plug in the value of the variable, a, and solve.
[tex]\mathrm{\displaystyle\frac{35}{a} }\\\mathrm{\displaystyle\frac{35}{7} }[/tex]
Now, divide:
[tex]\mathrm{5}[/tex]
Therefore, the final answer is
[tex]\mathrm{5}[/tex]
I hope it helps.
Have a nice day.
