Hey there!

The answer to your question is  45\frac{9}{10}

We can find this by simply plugging in the "r" value into the given equation.

46 + \frac{1}{5} (\frac{-1}{2})

Now we evaluate the equation:

46 + \frac{1}{5} (\frac{-1}{2})

46 + \frac{-1}{10}

45\frac{9}{10}

Hope this helps and have an amazing day!

Answer:

45\frac{9}{10} or 45.9

Step-by-step explanation:

All we have to do here is substitute the given value of r into the given expression. Therefore, after substituting r=-\frac{1}{2} into 46+\frac{1}{5}r, we get:

46+\frac{1}{5}r

= 46+\frac{1}{5}*(-\frac{1}{2} ) (Substitute r=-\frac{1}{2} into 46+\frac{1}{5}r)

=46-\frac{1}{10} (Multiply)

=45\frac{9}{10} or 45.9 (Simplify)

Hope this helps!
