Which of the following expressions demonstrates the distributive property?
O
3+4 +5 = 4 +3+5
-2(5 + 7) = -217 +5)
O3(-8 + 1) = 3(-8) + 3(1)
6[(7)(-2)] = [(6)(7)](-2)

3(-8+1)=3(-8)+3(1)

Step-by-step explanation:

distributive property is the rule that an equation consiting of a number next to perentheces with no sign inbetween the 2 with 2 or more values in said perenthecees is solved by multiplying the outside number by each value in the ( ) individually, without changing the signs or symbols

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:

(-5,-28)
