write and solve equations.
matt has 14 times as many cards as kal.
how many cards does matt have?
kal has 28 baseball cards.

Step-by-step explanation:

Let N, J, K, M represent the numbers of cards that Martin, Josie, Kal, and Matt have, respectively.

Equations

We are told ...

  N = 12J

  J = 29 +K

  M = 14K

  K = 28

__

Solution

Working from the bottom up, ...

  M = 14·28 = 392

  J = 29 +28 = 57

  N = 12J = 12·57 = 684

__

The answers to the questions asked are ...

  Martin has 684 baseball cards; Matt has 392 baseball cards.

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.
