A student was asked to rewrite using only the associative property of multiplication. Which is the correct response?

tatiyna

Given that the associative property of multiplication says that you can group the numbers in any combination, we can reorganize the expression as: 7·(10·3)=210. So the answer would be the first option.

Which solution to the equation StartFraction 1 Over x minus 1 EndFraction = StartFraction x minus 2 Over 2 x squared minus 2 End

Darina [25.2K]

Answer:

x = - 4

Step-by-step explanation:

Given the expression

$\frac{1}{x-1} = \frac{x-2}{2x^2-2}$

This can also be expressed as;

$\frac{1}{x-1} = \frac{x-2}{2(x-1)(x+1)}\\1 = \frac{x-2}{2(x+1)}$

Cross multiply

$2(x+1) = x - 2\\2x+2 = x-2$

Add 2 to both sides

$2x+2+2 = x-2+2\\2x+4 = x\\2x-x = -4\\x = -4$

Hence the required extraneous solution is x = -4

What is the value of -1/6+2/3(9-3/4)-1/2

Yuki888 [10]

$\bf -\cfrac{1}{6}+\cfrac{2}{3}\left( 9-\cfrac{3}{4} \right)-\cfrac{1}{2}\impliedby recall\qquad \mathbb{PEMDAS}
\\\\\\
-\cfrac{1}{6}+\cfrac{2}{3}\left( \cfrac{36-3}{4} \right)-\cfrac{1}{2}\implies -\cfrac{1}{6}+\cfrac{2}{3}\left( \cfrac{33}{4} \right)-\cfrac{1}{2}
\\\\\\
-\cfrac{1}{6}+\cfrac{2\cdot 33}{3\cdot 4} -\cfrac{1}{2}\implies -\cfrac{1}{6}+\cfrac{66}{12} -\cfrac{1}{2}\impliedby \textit{LCD of 12}
\\\\\\
\cfrac{-2+66-6}{12}\implies \cfrac{58}{12}\implies \cfrac{29}{6}\implies 4\frac{5}{6}$
