The fancy feet dog kennel has twice as many large breed dogs as small breed dogs. there are 10 large breed dogs. write the equation for the total number of dogs. let d = the number of sogs board at the fancy feet dog kennel. a. d = 2(10 + 10) b. d = 10 + 1/2(10) c. d = 1/2(10) + 2(10) d. d = 1/2(10 + 10)
