Answer:
Explanation:
To evaluate the expression for v = -6 / 7, we put this value in instead of v to get
[tex]-12\frac{1}{2}-3(-\frac{6}{7})[/tex]
Which upon simplification becomes
[tex]-12\frac{1}{2}+\frac{6\cdot3}{7}[/tex][tex]-\frac{25}{2}+\frac{6\cdot3}{7}[/tex][tex]=-\frac{25}{2}+\frac{18}{7}[/tex][tex]=-\frac{139}{14}[/tex]
which is our answer!
