8. An animal shelter has 50 dogs. The ratio of dogs to cats is 6:3. How many cats are at the shelter? 9. Triangles EFG and QRS are similar. The length of the sides of EFG are 144, 128, and 112. The length of the
smallest side of QRS is 280, what is the length of the longest side of ORS? (draw a diagram and solve)
10. A person 2 m tall casts a shadow 5 m long. At the same time, a building casts a shadow 35 m long. How tall is
the building? (draw a diagram and solve)

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.
