Simplify the expression.

sergiy2304 [10]

Answer:

The simplified expression is:

⇒ $13x-8$

Step-by-step explanation:

Given expression:

$(9x + \frac{1}{2})+(4x-8\frac{1}{2})$

To simplify the given expression.

Solution:

In order to simplify, we will combine the like terms by removing the parenthesis.

We have:

⇒ $9x + \frac{1}{2}+4x-8\frac{1}{2}$

Combining like terms.

⇒ $9x+4x+\frac{1}{2}-8\frac{1}{2}$

⇒ $13x+\frac{1}{2}-8\frac{1}{2}$

In order to combine fractions, we will combine the whole number and the fraction separately.

⇒ $13x-8+(\frac{1}{2}-\frac{1}{2})$

⇒ $13x-8+0$

Thus, the simplified expression is:

⇒ $13x-8$

FIND THE RECIPROCAL OF 3 4/9

Bas_tet [7]

Answer:

9/31

Step-by-step explanation:

For a fraction, the reciprocal is just a different fraction, with the numbers "flipped" upside down (inverted). Any number times its reciprocal will give you 1.

$3\frac{4}{9} * \frac{9}{31} = 1$
