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>
<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

Answer:
-11.75  - x
Step-by-step explanation:
0.5 squared = 0.25
0.25-12= -11.75
-11.75 - x
