Agroup of mountain climbers begin an expedition with 250 pounds of food. they plan to eat a total
of 12 pounds of food per day. write and solve a linear equation to find the number of days their
food will last.

The answer is:

Step-by-step explanation:

Given: 250 lbs of food to start.

Let d = number of days.

250/d = Total days

They eat 12 lbs per day.

Substitute to get the number of days it will last:

250 / 12 = 20.83 days the food will last

Hope this helps :-)

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.
