Answer:

She made a mistake in Step 7.

Step-by-step explanation:

Step 1 through 6 are correct. Only from Step 6 to Step 7 the problem comes in: both sides of the equation are multiplied by x, however the x on the left side, by error, becomes 1. The correct state in Step 7 should look like this:

$x(\frac{1}{2}P-x)=256$

If 40% of a number is 56 what was the original number

lisov135 [29]

$\begin{array}{ccc}100\%&-&x\\40\%&-56\end{array}\ \ \ |cross\ multiply\\\\40x=56\times100\\40x=5600\ \ \ \ \ |divide\ both\ sides\ by\ 40\\\\\boxed{x=140}$

Graph the system of equations on your graph paper to answer the question

UNO [17]

Since we have to solve this system graphically, we'll have to draw both lines.

To draw a line, simply build a little tables with two x,y values: for the first line we have

$\begin{array}{c|c}x&-x+3\\0&3\\1&2\end{array}$

So, you can draw the points (0,3) and (1,2), connect them, and you'll have the graph of the line $y=-x+3$

For the second line we have

$\begin{array}{c|c}x&x+5\\0&5\\1&6\end{array}$

So, you can draw the points (0,5) and (1,6), connect them, and you'll have the graph of the line $y=x+5$

Finally, we have to check where the two lines cross. If your drawing is accurate enough, you'll see that the point you're looking for is (-1, 4)
