Explain why you might want to write very large and very small numbers like the ones in the example problem in scientific notatio

slava [35]

Answer:

Extremely large and small numbers that have many zeros are long to write and take up a lot of room. So, by using scientific notation a number can be written shorter. For example, numbers such as 295,000,000,000 can be shortened to 2.95x $10^{11}$ . This is easier to write and understand. This is why the scientific notation is used over standard.

Equations with variables on both sides<br> 2 + 8x - 4 = 6.25x + 26

SSSSS [86.1K]

Answer:

x=16

Step-by-step explanation:

$2 + 8x - 4 = 6.25x + 26 \\ 8x - 6.25x = 26 - 2 + 4 \\ 1.75x = 28 \\ x = 28 \div 1.75 \\ x = (28 \div1) \div (175 \div 100) \\ x = (28 \times 100) \div (175 \times 1) \\ x = 2800 \div 175 \\ x = 16$
