In the past century or so, astronomy has been broadly split into two camps — observational astronomy (using telescopes and cameras to collect data about the night sky) and theoretical astronomy (using that data to analyze, model and theorize about how objects and phenomena work)

Well observational and theoretical astronomy are the two fields of professional astronomy. Observational astronomy is concerned with gathering information from observations of celestial objects. The data is then examined using fundamental physics principles.

Based on the diagram, fossils from how many geologic periods can be found in Virginia?
Eddi Din [679]

The correct answer is - 11.

According to the diagram, in Virginia can be found fossils from 11 geologic periods. That can easily be seen on the graph and the legend bellow it. The legend tells us which period is marked with which color. There's 11 periods on the legend, thus 11 different colors, and on the graph they are all represented, some more some less, but they are there.

This means that in Virginia can be found fossils from all sorts of marine life and terrestrial life from the present back two few hundred million years ago.

4x+28=2x+24+2x+2 slove for x
Alinara [238K]

The answer you are looking for is x = 0 (or undefined)

To solve for x, you would first combine all the like terms on the right side. To do so, add 2x and 2x to get 4x and add 24 and 2 together to get 26. This will give you 4x + 28 = 4x + 26, which you can now solve.

To find x, you would get the x by itself. However, in doing so you would get 0 or 0x. This is because you would subtract 4x on both sides to cancel out the 4x on the right, but in this case, it will also cancel out the 4x on the left. Thus meaning the answer is 0 or undefined.

I hope this helps!
