     12. 2ay -- x ay - b Solve for x 13. 20 is what % of 80? 14. Your patient\'s temperature is 98.6 degree Fahrenheit. What id that in 15. What is the area of a circle with a diameter of 10 mm? 16. What is the area of a rectangle with a length of 19 cm and a w  
  
  Solution
12). 2ay - x = ay - b
x = 2ay - ay + b = ay + b
x = ay + b
13). x% of 80 = 20
x = (20*100)/80 = 25
14). 98.6 fahrenheit = 37 celsius
15). area of circle = pi(d/2)2 = pi(10/2)2 = 25pi = 78.5 mm2
16) area of rectangle = length of reactangle * width of rectangle,
*width of rectangle is not display
