25. The Jones family is designing their new garage and workshop. The workshop will be a smaller square attached to the larger square garage. The sides of the garage are 4 times as
long as the sides of the workshop, and the sum of the areas of the two squares is 612 square
feet. How long are the sides of the workshop and the garage?

Step-by-step explanation:

each side of workshop = x

area of workshop = x²

each side of garage = 4x

area of garage = (4x)² = 16x²

total area = x² + 16x² = 17x²

17x² = 612

x² = 36

x = √36 = 6 ft

each side of workshop = 6ft

each side of garage = 24ft

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:

answer: 40.95
