The associative property is:
A + B + C = A + (B + C) = (A + B) + C
And a option that uses this is:
-4i + i + 4i- i = (-4i + 4i) + (i - i)
<h3>
Which equation shows an example of the associative property of addition?</h3>
The associative property says that we can write:
A + B + C = A + (B + C) = (A + B) + C
So, we can perform the sum in any order we want to.
Then for the given case we would have:
-4i + i + 4i- i = (-4i + 4i) + (i - i)
Where we sum in the order we want to get it equal to zero.

1. You need to change these so that they share a common denominator (bottom of the fraction)
2. Common denominator is 10 of these 2 fractions.
3. We don't need to change the 7/10 fraction because the denominator is already 10.
4. To make 1/2 have a denominator of 10, we need to times the top and bottom by the same number. To get 10 from 2, we have to times it by 5. Therefore, to change the top, we need to times it also by 5
5. 1 x 5 = 5
6. Add the two fractions together: 5/10 + 7/10 = 12/10
7. Simplify the expression. This is currently a top heavy fraction aka. improper fraction. To make it 'proper' we need to change it into a mixed number. To do this, we see how many of the bottom number goes into the top. In this case it is 1 with 2 left over. So the final fraction is...
1 2/10

Answer:
W=10 initially every volunteer had 10 total of 50 flyers she took 2 from each so 50-10 that's why they were left with 40
Hope this helps
Answer. 332.78
Step-by-step explanation:
I subtracted and as awesome its right trust me.
1. {2x−3y=9
{3x+5y=4
2. {(2x−3y=9)×5
{(3x+5y=4)x3
3. {10x-15y=45
{9x+15y=12
4. (10x-15y=45) + (9x+15y=12)= (19x=57)
5. (19x=57)÷19
6. x=3
7. 2(3)-3y=9
8. 6-3y=9
9. -3y=9-6
10. (-3y=3)÷(-3)
11. y=-1
Answer: x=3 and y=-1
