Answer:
Step-by-step explanation:
× A = <u>4y + 2</u> = 2(4y/2 + 2/2) = 2(2y + 1) ≠ 4(y + 2)
✓ B = <u>4y + 8</u> = 4(4y/4 + 8/4) = 4(y + 2) = 4(y + 2)
× C = y + y + y + y + 2 =
y (1 + 1 + 1 + 1) + 2 = <u>4y + 2</u> = A ≠ 4(y + 2)
✓ D = 5(y + 2) – (y + 2) = 5(y + 2) – 1(y + 2) =
(5 – 1)(y + 2) = 4(y + 2)
✓ E = y + y + y + y + 2 + 2 + 2 + 2 =
y (1 + 1 + 1 + 1) + (2 + 2 + 2 + 2) =
<u>4y + 8</u> = B = 4(y + 2)
× F = 5(y + 2) – (y – 2) =
(5y + 10) + (-y + 2) =
(5y – y) + (10 + 2) =
4y + 12 = 4(y + 3) ≠ 4(y + 2)
Answer: Arrows are used to show the feeding relationship between the animals.
Step-by-step explanation: The arrow points from the organism being eaten to the organism that eats it.

Answer: Barbara’s stand has the better buy
Explanation:
Als stand:
6 tomatoes = 0.9$
1 tomato = 0.9/6
1 tomato = 0.15$
Barbara stand:
11 tomatoes = 1.54$
1 tomato = 1.54/11
1 tomato = 0.14$
Thus, Barbara stand is cheaper and can sell a lot better than Als’s stand.
