*Appeared 3 to 4 million years ago in souther and eastern Africa.
*Humanlike creatures called primates
*Mary and Louis Leakey excavated hominid fossils in the Great Rift Valley
*"Lucy," and Australopithecine fossil, found in 1974.
*Three major differences from earlier primates: bipedalism (gives ability to walk upright), a sizable brain (enables abstract thought and fine motor control), and a larynx (allows for complex speech)
*Thought-processing ability led to alteration of the natural environment to suit human needs
I think it’s D hope that helped
The answer is B because I got it
Answer:
Explanation:
Answer:
Reorder the terms:
8 + 6p + -4p = 3(p + 4)
Combine like terms: 6p + -4p = 2p
8 + 2p = 3(p + 4)
Reorder the terms:
8 + 2p = 3(4 + p)
8 + 2p = (4 * 3 + p * 3)
8 + 2p = (12 + 3p)
Solving
8 + 2p = 12 + 3p
Solving for variable 'p'.
Move all terms containing p to the left, all other terms to the right.
Add '-3p' to each side of the equation.
8 + 2p + -3p = 12 + 3p + -3p
Combine like terms: 2p + -3p = -1p
8 + -1p = 12 + 3p + -3p
Combine like terms: 3p + -3p = 0
8 + -1p = 12 + 0
8 + -1p = 12
Add '-8' to each side of the equation.
8 + -8 + -1p = 12 + -8
Combine like terms: 8 + -8 = 0
0 + -1p = 12 + -8
-1p = 12 + -8

Measure the amount of certain radioactive elements in the rock when rocks are formed, small amounts of radioactive elements usually get included as the rock ages, more and more of the uranium changes into lead.
