True or false:
the iceman died from natural causes

The Iceman died in prison from natural causes.

True.

I believe the correct answer is true

I think I remember it was said that he had gotten shot by an arrow but he died from the snow storm and cold. (if you're talking about that frozen iceman named Otzi)

food chain i would say only because there is competition on getting food and survival

simplify brackets

8 - 2a - 7 = a + 40

simplify 8 - 2a - 7 to -2a + 1

-2a + 1 = a + 40

add 2a to both sides

1 = a + 40 + 2a

simplify a + 40 + 2a to 3a + 40

1 = 3a + 40

subtract 40 from both sides

1 - 40 = 3a

simplify 1 - 40 o -39

-39 = 3a

divide both sides by 3

-39/3 = a

simplify 39/3 to 13

-13 = a

switch sides

a = -13
