Which equation demonstrates the additive identity property?

Mathematics
1 answer:
Orlov [11]2 years ago
4 0

Answer:

(7+41)+0= 7+41

Step-by-step explanation:

Given the list of options A to D

Required: Select the one that shows additive identity property

The additive identity property is such that when 0 is added to an expression or a number, the expression or number remains unchanged and maintains its original value

This is represented as follows

a + 0 = a

(a + b) + 0 = a + b

So, from options A through D, the only option that fits the analysis above is (7+41)+0= 7+41.

Hence, we can conclude that (7+41)+0= 7+41 demonstrates an additive identity property

Write an equation of the circle with center (-3, 4) and radius 6.
Sedaia [141]

Answer:

(x+3)²+(y-4)²=36.

Step-by-step explanation:

For this, we need to use the equation of a circle which is:

(x-h)²+(y-k)²= r²

Simply substitute the center values for 'h,k', and the radius for 'r'.

This will give you:

(x+3)²+(y-4)²=36.

In the contiguous United States, the ratio of states that border an ocean to states that do not border an ocean is 7:9. How many
Luda [366]

Answer:

21

Step-by-step explanation:

The contiguous U.S. consist of all states beside Alaska and Hawaii; therefore, there are 48 contiguous U.S. states. However, the ratio given to us only consists of 16 states [7 + 9 = 16]. If we need to expand the ratio, we multiply 16 by 3 to get 48. Thus, we also multiply each of the terms by 3, and the ratio becomes 21:27. Therefore, the number of contiguous U.S. states that border an ocean is 21.

22=11x (subtract 3x and add 5 to both sides)

2=x (divide both sides by 11)
