Evaluate 5 - t/3 when t =12

1

Step-by-step explanation:

Plug in t = 12 in the expression

         = 5 - 4/1

          = 5 - 4

           = 1

Step-by-step explanation:

The value of in the expression is 12.

Replace the variable with 12.

Evaluate the expression.

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:

a .4y4
