Scientific notation is used to write really large numbers, or really small numbers using less digits. For example:

1. Earth's distance from the sun 150,000,000 kilometers. We can rewrite this in scientific notation as 1.5 x $10^{8}$

2. The length of a skin cell is 0.00003 meters. We can rewrite this in scientific notation as 3.0 x $10^{-5}$

3. The world population is about 7,000,000,000. We can rewrite this in scientific notation as 7 x $10^{9}$

Solve the absolute value equation 2x-4>5

lawyer [7]

Hello.

The answer is: X=9/2

Step 1: Add 4 to both sides.

2x−4+4>5+4

2x>9

Step 2: Divide both sides by 2.

2x/2>9/2

X>9/2

Have a nice day
