The answer might be 1/30 ( one over 30)
For this case we propose a system of equations:
x: Variable representing the weight of large boxes
y: Variable that represents the weight of the small boxes
So
![x + y = 80\\55x + 70y = 4850](https://tex.z-dn.net/?f=x%20%2B%20y%20%3D%2080%5C%5C55x%20%2B%2070y%20%3D%204850)
We clear x from the first equation:
![x = 80-y](https://tex.z-dn.net/?f=x%20%3D%2080-y)
We substitute in the second equation:
![55 (80-y) + 70y = 4850\\4400-55y + 70y = 4850\\15y = 450\\y = 30](https://tex.z-dn.net/?f=55%20%2880-y%29%20%2B%2070y%20%3D%204850%5C%5C4400-55y%20%2B%2070y%20%3D%204850%5C%5C15y%20%3D%20450%5C%5Cy%20%3D%2030)
We look for the value of x:
![x = 80-30\\x = 50](https://tex.z-dn.net/?f=x%20%3D%2080-30%5C%5Cx%20%3D%2050)
Large boxes weigh 50 pounds and small boxes weigh 30 pounds
Answer:
Large boxes weigh 50 pounds and small boxes weigh 30 pounds
Answer:
a line parallel to this line would be y=3
Step-by-step explanation:
parallel lines have the same slope, but different y-intercepts.
the slope of the line that passes through (4, 9) and (11, 9) is 0.
the equation is y = 9.
and that is identical to y = 3, because they both do not have a slope; they both form straight horizontal lines across the graph.
