4n=1/2(2n-12) check the solution to the example problem by replacing n in the original equation with -2 and evaluating both sides. what true statement do you get?

The true statement is that the expression is satisfied for n = -2.

Step-by-step explanation:

Given:

To check:

Left hand side = Right-hand side ( for n = -2)

Proof :

For n = -2

Consider  Left hand side of the equation given above.

∴ Left hand side = 4n

                            = 4×(-2)   ......................for n = -2

                            = -8

Consider Right-hand side of the equation given above

∴ Right-hand side =

Now we get Left hand side equal to Right hand side

i.e. Left hand side = Right hand side

i.e. is true for n = -2

step-by-step explanation:

68÷5=13.6

13.6×30=408min=6 hours 48 min.

hope to and hope that my answer is brainliest.(follow me )

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.
