Question

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

Answer 1

Hey there!

The answer to your question is
`45(9)/(10)`

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

46 +
`(1)/(5)` (
`(-1)/(2)`)

Now we evaluate the equation:

46 +
`(1)/(5)` (
`(-1)/(2)`)

46 +
`(-1)/(10)`

`45(9)/(10)`

Hope this helps and have an amazing day!

Answer 2

`45(9)/(10)` or
`45.9`

Explanation:

All we have to do here is substitute the given value of
`r` into the given expression. Therefore, after substituting
`r=-(1)/(2)` into
`46+(1)/(5)r`, we get:

`46+(1)/(5)r`

`= 46+(1)/(5)*(-(1)/(2) )` (Substitute
`r=-(1)/(2)` into
`46+(1)/(5)r`)

`=46-(1)/(10)` (Multiply)

`=45(9)/(10)` or
`45.9` (Simplify)

Hope this helps!
