PLEASE HELP! 28 POINTS AND GIVING BRAINLIEST Based on the decline of the population of the wolf population in 1920, indicate if the amount of each organism in the table below increased or decreased due to the removal of the wolves by 1920, and the reintroduction of the wolves in 1995. Use an up arrow (↑) to indicate an increase, and a down arrow (↓) to indicate a decrease. The first one has been done for you.

i think the answer is a and i hope this ; ))

8 - (2a + 7) = a + 40     distribute/multiply - into (2a + 7)

8 - 2a - 7 = a + 40

1 - 2a = a + 40       add 2a on both sides

1 = 3a + 40         subtract 40 on both sides

-39 = 3a       divide 3 on both sides

-13 = a

[proof]

8 - (2a + 7) = a + 40

8 - (2(-13) + 7) = -13 + 40

8 - (-26 + 7) = 27

8 - (-19) = 27

8 + 19 = 27

27 = 27

the answer should be founding brothers. i hope i you!

they were all fought in the middle east during ww1
