30:2...this is the ratio in decimal form.
The result of this ratio is 15.
Remember it can also be written as a fraction too--> 30/2
Answer:
x=4
Step-by-step explanation:
Hello keirabug, I am here to answer your question:
Since 10^3 is the same as 10*10*10, or 1000, and each CD is worth 12$, then 1000 * 12$ is equal to 12000$
But for the CD players, it's 10^2 or 10*10, which gives us 100, and each CD player is worth 35$, so 100 * 35$ is equal to 3500$
And then we do an addition to add the prices like this: 12000$ + 3500$ = 15500$
So the answer is 15500$
Hope this helped you!
Answer:
D
Step-by-step explanation:
So we have the equation:

And we want to find out which of the answer choices is <em>not</em> equivalent.
Thus, let's go through each of the choices.
A)
We have:

This is correct.
Our original equation can be written as:

And if we multiply straight across:

We'll get choice A. So choice A is correct.
B)
We have:

This is also correct.
From our original equation:

If we multiply the first term together:

We'll get choice B. So, choice B is correct.
C)
We have:

This is correct as well.
If we reduce 1/2 to decimal form and add the operations within the parentheses in the original equation, we will get:

So, C is also correct.
D)
We have:

Note that this is not correct.
This attempted to use the distributive property. However, the distribute property does <em>not work</em> for multiplication. For instance:

However:

So, choice D is not equivalent.
So choice D is our answer :)
If we evaluate it, we will get 30, in contrast to the 60 of the others.
