Choose the correct algebraic equation to represent: the amount decreased by $9 is $42.

vichka [17]

m - 9 = 42

42 is our final answer so that should be by itself.

If something is being decreased by 9, that means that we are taking away 9 from something so it should be m - 9.

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

loris [4]

The reciprocal property is:

$\frac{x - 3}{12} = \frac{x + 3}{20}$

Solution:

Given that,

$\frac{12}{x - 3} = \frac{20}{x + 3}$

The reciprocal property is given as:

The reciprocal of a fraction is the numerator and denominator switched

$\frac{a}{b} = \frac{c}{d}\\\\Then\\\\\frac{b}{a} = \frac{d}{c}$

Therefore,

$\frac{12}{x - 3} = \frac{20}{x + 3}$

By reciprocal property,

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

The we get,

$\frac{x - 3}{12} = \frac{x + 3}{20}$

Thus option C is correct
