Answer: 2p+1.50=11.50

               p = 5.00

<u>Step-by-step explanation:</u>

<em>Note: the tip is calculated on top of the total so this figure is a redherring</em>

<u>2 pancakes</u> <em>plus</em> <u>1 fruit cup</u> <em>equals</em> <u>total bill</u>

          2p       +        1.50          =         11.50

2p + 1.50 = 11.50

<u>      - 1.50 </u> <u> - 1.50  </u>

 2p         = 10.00

<u>÷2          </u>    <u> ÷2       </u>

    p         =  5.00

daser333 [38]

Answer:m

M=11/2

Step-by-step explanation:

Slope is equal to the change in y over the change in x, or rise over run.m=change in y change in x The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).m=y2−y1x2−x1 Substitute in the values of x

and y into the equation to find the slope.m=−4−(7)−6−(−4)
