I need the answers pls!

Given:

The equation is

To find:

The reason for second step.

Solution:

We have,

Using multiplication property of equality, multiply both sides by 3.

Using addition property of equality, add 4 on both sides.

Using division property of equality, divide both sides by 2.

So, the reason for second step is multiplication property (=).

Therefore, the correct option is D.

answer is:

1.75 pounds

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.
