Louisa states that the solution to the equation 1/4x - 3 = 3/8x + 4 is x = 56. she verifies her solution using the steps below.
equation: 1/4x - 3 = 3/8x + 4
step 1: 1/4(56) - 3 = 3/8(56) + 4
step 2: 14 - 3 = 21 + 4
step 3: 11 = 25
which statement most accurately describes louisa’s error?
a. louisa made an error when determining the original solution of x = 56.
b. louisa made an error when substituting the solution in for x.
c. louisa made an error when multiplying 56 by 1/4 and by 3/8
d. louisa made an error when adding or subtracting.

A. Louisa made an error when determining the original solution of x = 56.

Step-by-step explanation:

1/4x - 3 = 3/8x + 4

To verify x=56 is a solution, substitute x=56 into the equation

1/4(56) - 3 = 3/8(56) + 4

Multiply

14 -3 = 21 +4

Combine like terms

11 = 25

The steps are correct.

x=56 must not be a solution to the equation

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.
