Question

Evaluate the expression for the given value of the variable.
46 + 1/5r
r = -1/2

Answer 1

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!

Answer 2

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!
