Answer:

no solutions exist

Step-by-step explanation:

You can rewrite the denominator as:

-2(2x-6) so the equation becomes:

$-\frac12 \cdot \frac{2x-6}{2x-6} > 0$

from which you can see that not only should x ≠ 3, but for all values of x≠3 the equation is false.

Vilka [71]

Divide 25.7 by 141.

$\dfrac{25.7}{141} \approx 0.1822$

Now, multiply that with 100 percent to get the percentage.

$0.1822 \times 100 \%=18.22 \%$

18.22% is your answer! If the question wants you to round it to the nearest percent, the answer will be 18%.
