Determine whether the given value is a solution of the equation.

8w = 99; w = 12

The given value is NOT the solution of the equation.

Step-by-step explanation:

For the problem, we know that w = 12 and that when a variable is next to a number that means that multiplication should be used.  So, we will multiply 8 x 12 because w = 12 and we get 96.  This equation states that for this to be true 8w should equal 99.  So since 8w = 96 and not 99 we know this is incorrect.  

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.  

thats not a system of equations, that is a solution
