the lengths (in inches) of two sides of a regular pentagon are represented by the expressions 5x-27 and 2x-6. find the length of
fgiga [73]

Since the pentagon is regular, the sides are all of equal length. This tells you

... 5x-27 = 2x-6

... 3x = 21 . . . . . . . add 27-2x

... x = 7

The length of a side can be found by subtituting this value into either expression.

... 2·7-6 = 8 . . . . inches

Identify the property being shown here, assuming that a + 2 = y. <br> (a + 2)/3 = y/3
allochka39001 [22]

Assuming that <em>a + 2 = y</em>, the property that was applied to arrived at <em>(a + 2)/3 = y/3</em> is the: division property of equality.

<em><u>Recall:</u></em>

What is done to both sides of an equation will determine what property of equality was applied to the equation.

  • Thus, given the equation:

a + 2 = y

  • The following was obtained:

(a + 2)/3 = y/3

Observing the equation stated above, we will see that both sides of the equation was divided by three. This makes both sides equal.

Therefore, assuming that <em>a + 2 = y</em>, the property that was applied to arrived at <em>(a + 2)/3 = y/3</em> is the: division property of equality.
