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

15+2+13
Janelle used 30 pounds of fruit
Answer:
without the answer choices I can't give an awnser but I can tell you anything less then -5 will not be on there and if you are given a point of (x,y) then you can put in the x value and if it gives you that y value it will be correct
Therefore,
verified.
Hope you could get an idea from here.
