\frac{4}{ \frac{1}{4} - \frac{5}{2} }

To begin, we can simplify the expression's denominator by finding a common denominator between the denominators of the fractions in the denominator.  To make them compatible, we can convert \frac{5}{2} into \frac{10}{4}:

\frac{4}{ \frac{1}{4} - \frac{5}{2}( \frac{2}{2}) } = \frac{4}{ \frac{1}{4} - \frac{10}{4} }

Next, we can simplify:

\frac{4}{ \frac{1}{4} - \frac{10}{4} } = \frac{4}{ -\frac{9}{4}}

Finally, to cancel the denominator within the denominator, we can multiply the whole expression by \frac{4}{4}, or 1:

\frac{4}{ -\frac{9}{4}}* \frac{4}{4} =  -\frac{16}{9}

The expression simplifies to -\frac{16}{9}, or -1 \frac{7}{9} as a mixed number.

The step by step simplification is shown below.

\frac{4}{ \frac{1}{4}-\frac{5}{2}}  \\  \\ 
= \frac{4}{ \frac{1-2(5)}{4}  }  \\  \\ 
= \frac{4}{ \frac{-9}{4} } \\  \\ 
=4* \frac{-4}{9}  \\  \\ 
= - \frac{16}{9}

Therefore the answer is -16/9

Translate the phrase into a variable expression: twice the sum of a number and 5
DIA [1.3K]

Answer:

'Twice the sum of a number and 5' can be translated into variable expression such as:

  • 2(n + 5)

Step-by-step explanation:

Given the phrase

<em>Twice the sum of a number and 5</em>

First, let us breakdown the English Phrase

Let the number be = n

The sum of a number 'n' and 5 = n + 5

now, twice the sum of a number and 5 can be determined by multiplying (n+5) with 5.

Thus,

'<em>Twice the sum of a number and 5</em>' can be translated into variable expression such as:

  • 2(n + 5)
