A paper company needs to ship paper to a large printing business. The paper will be
Kryger [21]

Answer:

x = 8

y = 11

Step-by-step explanation:

Total small box weight  = 50x    [x being the number of small boxes]

Total large box weight = 80y     [y being the number of large boxes]      

Total boxes = x+y = 19

Total weight = 1280

<em>Determine x and y.</em>

<u>You know 2 equations. One for weight and another for number of boxes each.</u>

  • 1280 = 50x +80y
  • x+y = 19

<u>Rewrite second equation:</u>

x+y=19

y=19-x

<u>You have to plug in one into another.</u>

1280 = 50x + 80(19-x)

<u>Solve for x</u>

1280 = 50x + 1520 - 80x

-240 = -30x

x = 8

<u>Solve for y by plugging in x into one of the equations:</u>

8+y = 19

y = 11

C. s is your answer.

The sum of 2 angles on a straight line (supplementary angles) is 180°. Vertical angles (opposites where a line intersects) are equal.

The upper left and lower right angles where p crosses the other lines (q, r, t) are 105°.

180 - 105 = 75°

So the upper right and lower left angles are 75°. The lower left angle where p intersects s is 85°, so it is not parallel to the others.

Please let me know if you have any questions.
