<h3>(8.4 + 10.3) + (–4.1) = 8.4 + (10.3 + (–4.1)) is a example of associative property of addition</h3>
<em><u>Solution:</u></em>
Given that we have to find the associative property of addition

When we add, we can group the numbers in any combination
<em><u>Option A</u></em>
–(18.9 + 3.2) = –18.9 + (–3.2)
Here, negative sign outside the bracket is distributed to terms inside the bracket
This is not a example of associative property
<em><u>Option B</u></em>
–5.5 + 7.9 = 7.9 + (–5.5)
By commutative property of addition,
a + b = b + a
This, is commutative property of addition
<em><u>Option C</u></em>
–17.5 + 0 = –17.5
This is also not a example of associative property
<em><u>Option D</u></em>
(8.4 + 10.3) + (–4.1) = 8.4 + (10.3 + (–4.1))
We can group the numbers in any combination
This is a example of associative property of addition
The most simplest way to explain this is by breaking down the 60%.
Think about it.
If 60% space = 30 bikes
then 30% space = 15 bikes
then 10% space must be 5 bikes.
So we now know for sure 60% space = 30 bikes.
And 10% space = 5 bikes.
Then we know remaining 40% space = 20 bikes.
So total space = 100% space, for 50 bikes.

Step-by-step explanation:

Answer: x log[5] = log[125]
Explanation:
The original expression is 125 = 5^x
To express that as a logarithmic equation take logarithms on both sides:
log [125] = [log 5^x]
By the properties of the logartims of powers that is:
log [125] = x log[5]
And that is the equation required.
If you want to solve it, you can do 125 = 5^2, and apply the same property (logarithm of a power) to the left side, yielding to:
log [5^2 ]= x log[5]
=> 2 log[5] = x log[5]
=> 2 = x
