KengaRu [80]

Hey there! I'm happy to help!

We want to find how much money the lunch meat costs for one pound. We see that it costs $42.50 for 5 pounds, so we simply divide by 5 to see how much it costs for 1 pound.

42.5/5=8.5

Therefore, the answer is D. $8.50 per pound.

Have a wonderful day! :D

Dmitry_Shevchenko [17]

Answer:

x=-1/7

Step-by-step explanation:

\frac{3x-1}{3} -\frac{2x}{x-1} =x

\frac{(3x-1)(x-1)}{3x-3} -\frac{2x(3)}{3x-3} =x

\frac{3x^2-4x+1}{3x-3} -\frac{6x}{3x-3} =x

\frac{3x^2-10x+1}{3x-3} =x

\frac{3x^2-10x+1}{3x-3} =\frac{x(3x-3)}{3x-3}

\frac{3x^2-10x+1}{3x-3} =\frac{3x^2-3x}{3x-3}

3x^2-10x+1=3x^2-3x

-10x+1=-3x

-7x=1

x=-1/7
