Answer:

x = 9/25, y = 7/25, z = 4/25

Explanation:

step 1: solve for y in first equation to use substitution

y = -2x + 1

step 2: insert into second equation to eliminate y variable and work with two variables

3(-2x+1) + z = 1 (now distribute)

-6x + 3 + z = 1 (bring over the -3)

-6x + z = -2

step 3: now left with -6x + z = -2 and x + 4z = 1, so eliminate z

-6x + z = -2 (multiply by 4)

4(-6x + z = -2)

-24x + 4z = -8

-

x + 4z = 1 (brought down third equation)

-25x = -9

x = 9/25

then just plug in x into the third equation to solve for z, followed by plugging it into the first equation to solve for y. you should end with y = 7/25 and z = 4/25

In the 18th, 19th, and early 20th centuries, a wide variety of resistance movements across Asia and Africa fought against Europe
frutty [35]

Answer:

India's independence movement and revolts in Sudan.

Explanation:

These two campaigns are fought in all factors. The riots in Sudan were triggered by religion and brought out by violent processes. France had authority in Sudan, and the organizers of the faith-sponsored campaign attempted to overcome French rule. On the other hand, the old Indian freedom movement was not on a violent pathway. Civil disobedience, nonviolent protests were the main techniques of resistance. India's independence campaign is promoted by ethnicity and nationalism. So one campaign used violent and militant ways, while the other campaign used revolution and patriotism.

Compare and contrast the colonialist view of “genetic superiority” vs. Diamond’s view of New Guineans in terms of abilities? 

Eddi Din [679]
<span>Diamond is an evolutionary biologist, interested in adaptations, and he proceeds to speculate that New Guineans exhibit these heightened-mental-activity traits in response to their environment, which presents them with constant and varied challenges. He gets away with it because (1) this statement is buried inside his main thesis, which is in accord with the fundamental dogma (Western superiority is just an accident of geography), and (2) his superior racial  group is non-white, and it's okay to call whites inferior</span>
