Negative 7 and one over 8 minus negative 9 and one half is equivalent to the equation...
-7 + [tex] \frac{1}{8} [/tex] - (-9 [tex] \frac{1}{2} [/tex])
The first step would be to use the distributive property to simplify the equation.
-7 + [tex] \frac{1}{8} [/tex] + 9 [tex] \frac{1}{2} [/tex]
Next, you would add like terms.
-7 [tex] \frac{1}{8} [/tex] + 9 [tex] \frac{1}{2} [/tex]
2 [tex] \frac{3}{8} [/tex]
Your answer would be 2 [tex] \frac{3}{8} [/tex].
I hope this helps!
