Multiple choice question: Which equation demonstrates the identity property of multiplication? a* 1 = a
a* 2 = 2a
a* 0 = 0
a* (1/a) = 1

It is a*1=a

Step-by-step explanation:

This is because the identity property of multiplication states:

The product of 1 and any number is that number.

So therefore this equation represents the property

where a number A times 1 equals the number itself A.

so a*1=a is the correct answer

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:
