Help me write an inequality that would represent this statement!

8x+7<35

Step-by-step explanation:

8 times a number would be 8x the x being any number which is represented by the variable. increased by 7, I took as adding 7 and then put the less than sign and 35. 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.
