Ax 4 = e b ÷ 4 = e c + 4 = e d - 4 = e & a + b + c + d = 100 challenge what is the value of e ?

4A = E , A=E/4(1)

B/4=E , B=4E(2)

C+4=E, C=E-4(3)

D-4=E, D=E+4(4)

Substitute all values in 5th equation,

A+B+C+D=100  =  E/4 + 4E + E-4+ E+4 =100

 E/4 + 6E = 100

25E = 400

E=16 ANS

what does x eaqual

step-by-step explanation:

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
