Answer:

Option (B)

Step-by-step explanation:

x² + x - 1) x³ + 6x² + 0x + 5 ( x + 5

           - (<u>x³ +   x²  -  x</u>)

                      5x² + x + 5

                    -(<u>5x² + 5x - 5)</u>

                             -4x + 10

Result : x+5+\frac{-4x+10}{(x^{2}+x-1)}

By the comparing the result with the Lorie's solution,

She made a mistake in the last step in which she combined the constant incorrectly.

Therefore, Option (B) will be the answer.

Likurg_2 [28]
Hey there! :D 

So, we know that Jane received $9 out of the $30. 

Divide 9 by 30. 

9/30= .3

Turn that into a percentage. 

.3= 30%

We can check this by finding the other percentages. 

Ruth= 15  15/30= .5 50% 

Mary= 6 6/30= .2 20%

30%+20%+50%= 100% <== this works

I hope this helps!

artcher [175]
-3y + 5 = -4   Subtract 5 from both sides
      -3y = -9   Divide both sides by -3
         y = 3

Now, plug that into 5y

 5y    Plug in 3
5(3)   Multiply
 15

5y = 15
