Question:

It was recently estimated that homes without children outnumber homes with children by about 8 to 7. If there are 3870 homes in a county, how many of them are homes without children?

Answers

Answer: x = 2,340 homes without children There are 2,340 homes without children. Step-by-step explanation:'x' represent the number of homes without children 'y' represent the number of homes with children x : y = 9 : 7 Since the total number of homes is 4160 means x + y = 4160. From x + y = 4160 follows y = 4160 - x. Plug y = 4160 - x into x : y = 9 : 7 x : (4160 - x) = 9 : 7
