If I am reading the equations correctly, they are:
   5x - 14 = 3x   AND  7x + 12 = x - 6

If this is correct, the first one would be worked out like this:
   5x (- 5x) - 14 = 3x (- 5x)
   - 14 = - 2x
   - 14 (/ - 2) = - 2x (/ - 2)
   7 = x

The second would be worked out like this:
    7x + 12 (+ 6) = x - 6 (+ 6)
    7x + 18 = x
    7x (- 7x) + 18 = x (- 7x)
    18 = - 6x
    18 (/ - 6) = - 6x (/ - 6)
    - 3 = x

I hope this is what you are looking for :)

The number of pieces of popcorn in a large movie theatre popcorn bucket is normally distributed, with a mean of 1610 and a stand
romanna [79]

Answer:

A

Step-by-step explanation:

We know that in normal distribution, approximately 34% of bags will fall with in one standard deviation on one side. On both sides within the range of 1 standard deviation, 34 + 34 = 68 % of bags will fall.

Our range is:

1600 to 1620

1610 - 10 to 1610 + 10

So the answer is 1

That means, that 68% is the answer.
