Someone please help and explain it would really help

Mathematics
1 answer:
Vaselesa [24]3 years ago
8 0

So when you're solving for x here and distribute 8 on the right side, it would look like this:

8x+47=8(x+5)\\ \\ 8x+47=8x+40

Now in order to solve for x, we know we have to get all the x's on one side of the equal sign. Let's get all our x's to the left side. Since the right side has a positive 8x, you need to subtract 8x on the right. But whatever you do to one side you must do to the other. So since we are subtracting 8x on the right, we need to do that on the left.

But we can't! Since both sides will cancel out to zero before x can be solved.

Therefore the answer is 0.

Hope that helps!

if he allows 40 people to choose a treat from the bag about how many lizard lollis can he expect to give away
kirill [66]

Answer:

20 Lizard lollies.

Step-by-step explanation:

There are 10 lizard lollis.  This is out of 10+4+6 = 20 total treats.  This makes the probability of drawing a lizard lollis 10/20 = 1/2.

This means out of 40 treats handed out, we can expect him to give out 1/2(40) = 20 lizard lollis.

Combine like radicals to get your answer. <br><br> image attached
spin [16.1K]

Answer:

So the final answer is

-8\sqrt{3}

Step-by-step explanation:

Radicals:

In mathematics, a radical expression is defined as any expression containing a radical (√) symbol. Many people mistakenly call this a 'square root' symbol, and many times it is used to determine the square root of a number. However, it can also be used to describe a cube root, a fourth root, or higher.

The given expression is

-5\sqrt{3} -3\sqrt{3}

Now take common radical out so we will get

\sqrt{3}(-5-3)

Now add the Parenthesis part.

\sqrt{3}(-8)

So the final answer is

-8\sqrt{3}
