Answer:
There are four addition properties that help to add whole numbers :
For any whole number a, b, and c ;
1. <u>Closure property of addition </u>-
For example:
2+3=5
4+3=7
We can conclude that if we add any two whole number , we get another whole number.
2. <u>Associative property of addition</u>- when any whole number or variable are added, then that can be grouped in different way without changing result
For example:
2+(3+4)=(2+3)+4
3.<u> </u><u>Commutative property of addition</u>- when any whole number or variable are added, then the order changed without changing the result.
For example: 2+3=3+2
4. <u>Identity property of addition</u>- when 0 is added to a whole number or variable , the result is the same variable or number.
For example: 3+0=0+3
0 is called an Identity for addition of whole numbers.
Answer:
-80
Step-by-step explanation:
We have: -6 = + 4. In order to solve for x, we need to isolate it; in order to isolate x, we have to "undo" order of operations.
The regular order of operations is PEMDAS: parentheses, exponents, multiplication, division, addition, subtraction.
Here, since we're solving for x, we need to go backwards. So, first, subtract 4 from both sides:
-6 - 4 = + 4 - 4 ⇒ -10 =
Then, multiply by 8 on both sides:
-10 * 8 = * 8 ⇒ x = -80
Thus, x = -80.
Hope this helps!
