Simplify. (x6 y3)(−8xy2)(−6x3)

meriva

When simplifying this, we would have to take this little by little in serious steps and not only this, but to also take notice of the use of <u>pemdas</u> and to make sure that we take each step carefully.

We first would <u></u><u>(first)</u> simplify the following:

$(((x^6)*(y^3))*(0-(8x*(y^2))))*(0-(2*3x^3)) \\ \\ then \ we \ would \ do . . . . \\ \\ x^7 \ multiplied \ by \ x^3 \ = x^(^7^ +^ 3^) = \ x^1^0 \\ \\ (last \ step).... \\ \\ 2^3 \ multiplied \ by \ 2^1 = 2^(^3^ +^ 1^) = 2^4 \\ \\ \Longrightarrow \ (your \ answer) \\ \\ \boxed{\bf{ (2^4*3x^1^0y^5)}}$

The total bill for a dinner party was 134.03. Marcus pays 20.45 of the bill. The other people at the party divide the remaining

SCORPION-xisa [38]

Answer:

9 people

Step-by-step explanation:

Start by writing an equation.

The total bill is 134.03. The bill is totally paid by Marcus and the other guests. This will go on the other side of the equation.

Since we don't know how many guests there were, we can use variable x to represent the value that we're trying to find.

So here is our equation.

134.04 = 20.45 + 12.62x

Now, just solve for x, or isolate x.

Subtract 20.45 from both sides.

134.04 - 20.45 = 12.62x

Divide both sides by 12.62.

113.59/12.62 = x

Simplify.

x = 9

Since x is 9, we know that there were 9 other people at the dinner party.

Answer:

Note that $PQ + QR = PR$ :

Once:

$PR = 15x-11\\PQ=3x+6$

$PQ + QR = PR\\\\(3x+6)+QR=(15x-11)\\\\QR=(15x-11)-(3x+6)\\\\QR=15x-11-3x-6\\\\QR=12x-17\\$

Therefore, the answer is letter B
