Answer:

n= 42

Step-by-step explanation:

Given expression is: 3(n-5)-2(n+8)=11  

Now, first of all we will multiply the numbers which are outside the brackets to the numbers inside. Which will become:  

3n-15 - 2n - 16 = 11

Next the second step is to the change the positions. The numbers that are multiplied by n will be together:  

3n - 2n -15 - 16 = 11

Finally, by solving the above equation. We get:

n - 31= 11

n = 11+ 31  

n= 42

Required answer is n = 42

What is 778,400,000 in scientific notation?
FinnZ [79.3K]

When working with very large or very small numbers, scientists, mathematicians, and engineers use scientific notation to express these quantities. Scientific notation is a mathematical abbreviation, based on the idea that it is easier to read an exponent than to count many zeros in a number. Very large or very small numbers need less space when written in scientific notation because the position values ​​are expressed as powers of 10. Calculations with long numbers are easier to do when using scientific notation
