Answer:
x = 5, y = -2.
or as an ordered pair it's (5, -2).
Step-by-step explanation:
2x + 3y = 4
y = 5x - 27
-5x + y = -27 Multiply this by - 3:
15x - 3y = 81 Add this equation to the first equation:
17x = 85
x = 5
Plug this into the second equation:
y = 5(5) - 27
y = -2.

Answer:
I can't see the fine details of the image displaying the weights of the bags but I would assume the heaviest bag is 2(3/4) pounds, being Bag C. The lightest bag is most likely Bag B, being 2(3/8) pounds.
I'm assuming the deck is the shaded area.
To find the area of the deck, find the area of the large circle and subtract the area of the small circle from it:
A of large circle: R = (4.2/2) + 1.7 = 3.8; area: 3.8^2 * pi is about 45.3.
A of small circle: r = 4.2/2 = 2.1; area: 2.1^2 * pi is about 13.8
Now, subtract:
45.3 - 13.8 = 31.5 meters squared
