Tessa shot 36 free throws. she made 27 of them. what fraction of the free throws did she make?

For this case we have the following variables:

x: number of free throws that Tessa made

y: total number of free throws

We now write the relationship of free throws.

We have then:

Simplifying the expression we have:

The fraction of the free throws that she made is:

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:

b, i believe, but not sure.
