Answer: The apple costs 0.45
Step-by-step explanation: Oranges will be x in our equations and Apples will be y.
Anna's equation is: 3x + 6y = 4.5 (1)
Maria's equation is: 2x + 2y = 2.1 (2)
As we need to find y, we need to cancel x, this way, we multiply equation (1) by 2 and equation (2) by 3.
3x + 6y = 4.5 (x2)
2x + 2y = 2.1 (x3)
__________________
6x + 12y = 9
6x + 6y = 6.3
__________________
Now, we subtract them
6x + 12y = 9
-6x - 6y = -6.3
________________
6y = 2.7 → y = 2.7/6 → y = 0.45

Answer:
opposite sides have the same slope, so it is a parallelogram
Step-by-step explanation:
A parallelogram has opposite sides that are parallel. Here, one pair of opposite sides consists of horizontal lines. Both have zero slope, so are parallel.
The other pair of lines each has a "rise" of 3 units for each "run" of 2 units, so the lines have a slope of 3/2. Both lines have the same slope, so are parallel.
Since opposite sides are parallel, the figure is a parallelogram.
