Explanation:

The names of the eras in the Phanerozoic eon (the eon of visible life) are the Cenozoic ("recent life"), Mesozoic ("middle life") and Paleozoic ("ancient life"). The further subdivision of the eras into 12 "periods" is based on identifiable but less profound changes in life-forms.

It subdivides all time into named units of abstract time called—in descending order of duration—eons, eras, periods, epochs, and ages. The enumeration of those geologic time units is based on stratigraphy, which is the correlation and classification of rock strata

How to solve 2a-8a=12-8a
romanna [79]

Let's solve your equation step-by-step.

2a−8a=12−8a

Step 1: Simplify both sides of the equation.

2a−8a=12−8a

2a+−8a=12+−8a

(2a+−8a)=−8a+12(Combine Like Terms)

−6a=−8a+12

−6a=−8a+12

Step 2: Add 8a to both sides.

−6a+8a=−8a+12+8a

2a=12

Step 3: Divide both sides by 2.

2a

2

=
