There are 17 more girls than boys. there are 431 students in all. how many boys are there

Let g= number of girls, and b= number of boys

g = 17 + b

431 = g + b

so, after substitution

431 = (17+b) + b

431 = 17 + 2b

Solve for b, and you will get your answer.

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.  

y -5 = (-1/4)(x + 8)
