Write and solve a proportion to find the perimeter of a square when its side length is 12. Ty

Its 12 points

48

Step-by-step explanation:

setup a ratio using the length and perimeter then reduce it.

reduces to

the numerator is length and denominator is perimeter. setup the proportion

cross multiply

1 times p = p, so the answer is 48

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:

step-by-step explanation:

this is not a question
