Which is an example of the associative property?

Mice21 [21]

<h3>(8.4 + 10.3) + (–4.1) = 8.4 + (10.3 + (–4.1)) is a example of associative property of addition</h3>

Solution:

Given that we have to find the associative property of addition

$a + (b+c) =(a+b) + c$

When we add, we can group the numbers in any combination

Option A

–(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

Option B

–5.5 + 7.9 = 7.9 + (–5.5)

By commutative property of addition,

a + b = b + a

This, is commutative property of addition

Option C

–17.5 + 0 = –17.5

This is also not a example of associative property

Option D

(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

At the playground, 60% of the bike rack was filled. Thisis 30 bikes. How many total slots are there for bicycles?

Blizzard [7]

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.

Express 125 = 5x as a logarithmic equation.

Marizza181 [45]

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
