Help!! Which of the following uses the reciprocal property to rewrite 12/x-3 = 20/x+3?
A:12/x+3 = 20/x-3
B:x-3/20 = 12/x+3
C:x-3/12 = x+3/20
D:x-3/12 = 20/x+3

Respuesta :

The reciprocal property is:

[tex]\frac{x - 3}{12} = \frac{x + 3}{20}[/tex]

Solution:

Given that,

[tex]\frac{12}{x - 3} = \frac{20}{x + 3}[/tex]

The reciprocal property is given as:

The reciprocal of a fraction is the numerator and denominator switched

[tex]\frac{a}{b} = \frac{c}{d}\\\\Then\\\\\frac{b}{a} = \frac{d}{c}[/tex]

Therefore,

[tex]\frac{12}{x - 3} = \frac{20}{x + 3}[/tex]

By reciprocal property,

Switch the numerator and denominator of right side fraction as well as left side fraction

The we get,

[tex]\frac{x - 3}{12} = \frac{x + 3}{20}[/tex]

Thus option C is correct
