Question

a soccer team scored 2 goals in the first half. If they won the game by a score of 2 goals to 1 goal, how many goals did they score in the second half? Tell which property I used. The associative property,identity property or the communitive property.

Answer 1

They scored no goals because they scored 2 goals in the first half. They only scored 2 goals throughout the entire game and both were in the first half.

2+__=2
2+0=2
Identity Property

Answer 2

we know that

The identity property of addition, states that when you add zero to any number, it equals the number itself

Let

x---------> number of goals that a soccer team scored in the first half

y---------> number of goals that a soccer team scored in the second half

$x+y=2\\ x=2\\y=0$

so

$2+0=2$ ---------> identity property of addition

therefore

the answer is

identity property
