Choose the number sentence that shows the identity property of addition. a. 122 = 61 + 61 b. 62 = 1 + 61 c. 61 = 0 + 61

For this case we have that by definition, the property: Identity element of the zero-sum establishes:

Example:

The number "0" is the only element that retains the identity in the operation of the sum.

Thus, the equation: is an example of this property.

ANswer:

Option C

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

$15 each

step-by-step explanation:

$45/3 children= $15 each
