14=-(p-8) <br> how do i find p
Xelga [282]

Answer:

p=-6

Step-by-step explanation:

14 = -(p-8)   (distribute negative into parentheses)

14 = p(-1) -8(-1)

14 = -p + 8   (subtract 8 from both sides)

14 - 8 = -p

6 = -p   (multiply both sides by -1 and rearrange)

p = 6(-1) = -6

(a)
the list would be
-20, -12, -8, -1, 1, 5, 10
the other intergers would have to be greater than 1 in order to be on the correct side and cause 1 to be in the middle. They could be anything but 5 and 10 because these were already chosen.

(b)
the list would be like before
-3 was not included so one of the chosen would be -3 and the other would have to be less than -3 but not -8, -12, or -20 beacuse those were already chosen
