Question

What is the value of `3+y-:4`, when `y=16`?

Answer 1

The answer is `7.`

Explanation:

First, you plug the `y = 16` into the problem, so it looks like this:
`3 + 16 /4`

Then follow PEMDAS.
`3 + (16/4)`
`3 + (4)`
`7`

Answer 2

See below.

Explanation:

When solving this expression, first we need to remember to follow the Order of Operations .

This operation is commonly referred to as `PEMDAS`. This is an acronym used by many in a way to remember these important steps:

`P` - Parenthesis

`E` - Exponents

`MD` - Multiply/Divide (left to right)

`AS` - Add/Subtract (left to right)

Now that we know this, we can being to simplify this expression. Luckily for us, it has given us the value of `y`, so all we have to do is to plug said value into the expression:

`3+ydivide4 => 3+(16)divide4`

Now we simply solve using the above steps in order form top to bottom:

`3+(16)divide4`

`=3+4`

`=7`

Answer 3

`7`

Explanation:

Be careful about the order of operations.

There are two terms. Calculate an answer for each first, which means doing the division of the second term first.

`color(blue)(3)" "+" "color(red)(y div4)`

`=color(blue)(3)" "+" "color(red)(16 div4)`

`=color(blue)(3)" "+" "color(red)(4)`

`=7`
