Your friend has owned a dog for 11 years. This is one year less than 2 as long as he has owned a cat. How long has your friend owned a cat?

He pet the cat at least 13 years

Step-by-step explanation:

11 + 2 = 13

But less than 2 mean the dog's years is less cat's years 2 years, but less than can be more on cat, so if the number above 2 or equal 2, then it was right.

x >= 2

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
