How to solve 12ax-2ax+14x-2a+ -3x

1 answer:

8 0

That long, messy expression is not an equation and it's not a question,
so there's nothing to solve or answer. However, it IS long and messy, so
your homework assignment might be to 'simplify' it. Here's how:

12ax - 2ax + 14x - 2a + -3x

Everything we'll do to this is called "combine like terms". That means
"combine terms that are alike". Terms are alike when they have the
same letter variables.

12ax and -2ax are like terms. Combine them, and you get 10ax .

14x and -3x are like terms. Combine them, and you get 11x .

So now we have: 10ax + 11x + 2a .

Nothing has been changed. This shorter, simpler expression has
exactly the same value as the original long messy one has. It has
just been cleaned up, and it looks neater and simpler.

You might also be expected to 'factor' the expression. I don't know.
If you want to do that, then you could do it in 2 different ways . . .
either factor the 'x' from the two terms that have 'x' in them, or
else factor the 'a' from the two terms that have 'a' in them.
Without explanation, here's how those would look:

x(10a + 11) + 2a
or
a(10x + 2) + 11x .

Again, nothing has changed. Both of these have the same value, and
their value is the same as the value of the long messy expression in
the question.

Of the last 500 customers entering a supermarket, 50 have purchased a wireless phone. If the relative frequency approach for ass

Inessa05 [86]

Answer:

The probability that the next customer will purchase a wireless phone is 0.1

Step-by-step explanation:

The relative frequency approach states how often something happens divided by all outcomes.

In the example some of the customers entering a supermarket purchased a wireless phone.

Here all outcomes are 500 customer entering supermarket. And among these outcome purchasing wireless phone happened 50 times.

Then the probability that the next customer will purchase a wireless phone is

$\frac{50}{500}$ .

If we divide both sides by 50, we get $\frac{1}{10}$ =0.1

Rebecca has 12 photos she wants to hang side by side on her wall.A. If she only wants to display 8 of the photos, in how many wa

Mariana [72]

If she will choose 8 from 12 photos, the total number of ways she can choose is given by a combination of 12 choose 8, since the order of the photos doesn't matter.

The formula for a combination of n choose p is:

$C(n,p)=\frac{n!}{p!(n-p)!}$

For n = 12 and p = 8, we have:

$C(12,8)=\frac{12!}{8!(12-8)!_{}}=\frac{12\cdot11\cdot10\cdot9\cdot8!}{8!\cdot4!}=\frac{12\cdot11\cdot10\cdot9}{4\cdot3\cdot2}=495$

So there are 495 ways.

If she wants to arrange the 12 photos, the total number of ways is given by the factorial of 12:

$12!=12\cdot11\cdot10\cdot9\cdot8\cdot7\cdot6\cdot5\cdot4\cdot3\cdot2=479001600$

There are 479,001,600 ways.

Since 10 photos already have specific places, we need to calculate the number of ways to arrange the other two photos in the two remaining places.

In this case, there are only 2 ways of organizing the remaining two photos:

Photo 1 first, photo 2 last, or photo 1 last and photo 2 first.

Which expression shows the result of applying the distributive property to 3(2x−6)3(2x−6) ?

sattari [20]

Here is the answer. Given 3(2x−6) 3(2x−6), what we need to do is multiply 3 by 2x and -6 and this will give us this result. 6x-18 6x-18. Therefore, the answer for this is the first option. The expression that shows the result of applying the distributive property to 3(2x−6)3(2x−6) is 6x-18 6x-18.
