Translate the phrase into an algebraic expression.
adell [148]

Answer:

8 + \frac{5}{w}

Step-by-step explanation:

From the phrase, the <em>answer</em> is smaller(less) by 8  when compared(equal (=)) to quotient of 5 and w ...

So:

Answer - 8 = quotient of 5 and w

Here, quotient is the whole number from a <em>division</em>. The division here is \frac{5}{w}

Therefore,

Answer - 8 = \frac{5}{w}

Answer = 8 + \frac{5}{w}

Hence the phrase into algebraic expression is 8 + \frac{5}{w}
