Answer:
6)A.y = 4x
7)D.31kg
Step-by-step explanation:
6)5 means the monthly average weight gained by the dog
X means the months
Example:
X=3 or (3 months past when the dog was born)
y=5x
y=5(3)
y=15
so it means that the dog's weight after 3 months was 15 kg
7)So for a puppy that weighs 15 lbs at 5-months (22-weeks), his growth rate would be 15/22 = 0.68 To get his adult weight you'd multiply the growth rate by 52, i.e. 0.68 x 52 = 35.36. Based on this method, a puppy that weighs 15lbs at 5-months old would weigh about 35.36 lbs as an adult.
