Four times of a number diminished by five is thrice the number increased by seven. What is the number?

the number is 12

Step-by-step explanation:

4x-5=3x+7

x=12

x = 12

Step-by-step explanation:

Call the missing number x.

4x - 5 = 3x + 7

Subtract 3x from both sides

x - 5 = 7

Add 5 to both sides

x = 12 (ans)

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

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.
