Question

For positive values of x and n, x is n% of 20. Which expression represents n in terms of x?

  1. 100 open parentheses 80 over x close parentheses
  2. 100 open parentheses x over 80 close parentheses
  3. 100 open parentheses 20 over x close parentheses
  4. 100 open parentheses x over 20 close parentheses

The correct answer is: 100 open parentheses x over 20 close parentheses


    Given x = n% (20) equals n over 100 cross times 20
    x equals n over 100 cross times 20 semicolon n equals 100 over 20 cross times x equals 5 x
    Option D represents above equation, it is the option.

    In 2007, wind erosion was responsible for 0.77 billion tons of soil loss on cropland in the US. Sheet water erosion and rill water erosion were also responsible for soil loss on cropland. These three types of erosion were responsible for a total of 1.73 billion tons of soil loss. Which inequality represents the soil loss x, in billions of tons, on cropland from sheet water erosion in 2007?
