What's the Rule?
Fill in the table for this input-output rule:

1. 1

2. 2

3. -3

4. 51

Step-by-step explanation:

To do this, in each input number (I will represent the number as x), you have to do the number in the input number, x. You have to divide x by 2, then add 1.

x/2 + 1 would be the answer (this is an example).

1. 1

2. 2

3. -3

4. 51

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) 32pie square meters
