Answer:
x = 2, y = 1
Step-by-step explanation:
x + 4y = 6 and y = 3 - x have to be rearranged: x + 4y = 6 and x + y = 3
You subtract the equations to eliminate one of the variables (x) so that the other can be found
The (0, 3] is taken out of the picture leaving you with B.
We have given that,
Machine 1 can complete a task in x hours while an upgraded machine (machine 2) needs 9 fewer hours.
We have to determine the,
The plant manager knows the two machines will take at least 6 hours, as represented by the inequality
after you find the intervals.
you also need to consider that the plant manager knows the two machines will take at least 6 hours.
so (0, 3] is taken out of the picture leaving you with B.

Answer: 2,480 grams of sand
Step-by-step explanation:
There are 31 days in July.
Minh sweeps up 80 grams every day in July so at the end of July, Minh should have:
