Answer:
The correct answer is OB.
Step-by-step explanation:
Let us recall the Associative Property of Addition: given three real numbers 
, 
and 
the following equality holds:
.
Let us remark that the Associative Property of Addition tells us that we can perform the sums in any order. So,
.
In the other options there was used the Commutative Property of Addition.
2 - 2n = 3n + 17 > -2n = 3n + 15 > -5n = 15 > n = -3
Answer:
7/21
Step-by-step explanation:
Answer:
1560
Step-by-step explanation:
1200*0.075 = 90
1200+90+90+90+90
As we know these two lines mean | | a modulus sign. The modulus symbol is sometimes used in conjunction with inequalities. A modulus sign in simple words just ignores the sign and gives us the absolute value.
For example in this case the modulus gives us 4 x 2 - 3. As you can see the modulus sign has ignored the original negative signs with the numbers.
So after evaluating the equation the answer comes out to be 8 - 3 which is equal to 5.
