Ultimately, you want the <em>variable</em> p on one side of the equals sign, and the <em>value</em> of p on the other.

First, get rid of the parenthesis by <em>distributing.

</em>There is an invisible -1 in front of the first and last set of parenthesis, and a one times any number is the number itself, so you are essentially distributing the negative sign. 
<em>
</em>So you have:     2-4p-3 = -3p-6-2p-3
<em>
</em>Next, <em>Combine like terms.
</em>
Can you take it from there?<em>

Simplifying
2 + -1(4p + 3) = -3(p + 2) + -1(2p + 3)

Reorder the terms:
2 + -1(3 + 4p) = -3(p + 2) + -1(2p + 3)
2 + (3 * -1 + 4p * -1) = -3(p + 2) + -1(2p + 3)
2 + (-3 + -4p) = -3(p + 2) + -1(2p + 3)

Combine like terms: 2 + -3 = -1
-1 + -4p = -3(p + 2) + -1(2p + 3)

Reorder the terms:
-1 + -4p = -3(2 + p) + -1(2p + 3)
-1 + -4p = (2 * -3 + p * -3) + -1(2p + 3)
-1 + -4p = (-6 + -3p) + -1(2p + 3)

Reorder the terms:
-1 + -4p = -6 + -3p + -1(3 + 2p)
-1 + -4p = -6 + -3p + (3 * -1 + 2p * -1)
-1 + -4p = -6 + -3p + (-3 + -2p)

Reorder the terms:
-1 + -4p = -6 + -3 + -3p + -2p

Combine like terms: -6 + -3 = -9
-1 + -4p = -9 + -3p + -2p

Combine like terms: -3p + -2p = -5p
-1 + -4p = -9 + -5p

Solving
-1 + -4p = -9 + -5p

Move all terms containing p to the left, all other terms to the right.

Add '5p' to each side of the equation.
-1 + -4p + 5p = -9 + -5p + 5p

Combine like terms: -4p + 5p = 1p
-1 + 1p = -9 + -5p + 5p

Combine like terms: -5p + 5p = 0
-1 + 1p = -9 + 0
-1 + 1p = -9

Add '1' to each side of the equation.
-1 + 1 + 1p = -9 + 1

Combine like terms: -1 + 1 = 0
0 + 1p = -9 + 1
1p = -9 + 1

Combine like terms: -9 + 1 = -8
1p = -8

Divide each side by '1'.
p = -8

Simplifying
p = -8

I need help with this question
Bezzdna [24]

Answer:

It is all determined by how many spaces and which way the decimal point moves.

Step-by-step explanation:

So here are two examples

<em>Example 1:</em>

500000.00

To write this in scientific notation you would move the decimal place to the left.

You would move it 5 digits to the left so the exponent of 10 would be 5

5 * 10^{5}

<em>Example 2</em>

0.0000042

Here to write this in scientific notation you move the decimal place to the right.

You would move it 6 digits to the right so the exponent would be -6

4.2 * 10^{-6}

The number of typographical errors on a page of the first booklet is a Poisson random variable with mean 0.2. The number of typo
muminat

Answer:

The required probability is 0.55404.

Step-by-step explanation:

Consider the provided information.

The number of typographical errors on a page of the first booklet is a Poisson random variable with mean 0.2. The number of typographical errors on a page of second booklet is a Poisson random variable with mean 0.3.

Average error for 7 pages booklet and 5 pages booklet series is:

λ = 0.2×7 + 0.3×5 = 2.9

According to Poisson distribution: {\displaystyle P(k{\text{ events in interval}})={\frac {\lambda ^{k}e^{-\lambda }}{k!}}}

Where \lambda is average number of events.

The probability of more than 2 typographical errors in the two booklets in total is:

P(k > 2)= 1 - {P(k = 0) + P(k = 1) + P(k = 2)}

Substitute the respective values in the above formula.

P(k > 2)= 1 - ({\frac {2.9 ^{0}e^{-2.9}}{0!}} + \frac {2.9 ^{1}e^{-2.9}}{1!}} + \frac {2.9 ^{2}e^{-2.9}}{2!}})

P(k > 2)= 1 - (0.44596)

P(k > 2)=0.55404

Hence, the required probability is 0.55404.

qaws [65]

Answer:

  • £1.20

Step-by-step explanation:

<u>Given:</u>

  • Tea = x
  • Coffee = x + 0.2

<u>Comparing the total cost, work out the value of x:</u>

  • 2x + x + 0.2 = 3.80
  • 3x = 3.60
  • x = 1.20

Bo invests money in an account paying a simple interest of 8% per year. If no money will be added or removed from the investment
inn [45]

Answer:

Calculation:

First, converting R percent to r a decimal

r = R/100 = 8%/100 = 0.08 per year,

then, solving our equation

I = Prt (Where p=principle,r=rate,t=time)

I = p*0.08*1=0.08p

Solve for x. PLEASE HELP ASAP
Paha777 [63]

Answer:

x = 6

Step-by-step explanation:

the tangent- tangent angle UVW is half the difference of the intercepted arcs, that is

∠ UVW = \frac{1}{2} (UW - WU ) , then

5x + 17 = \frac{1}{2} (37x + 5 - (23x - 5) ) ← multiply both sides by 2

10x + 34 = 37x + 5 - 23x + 5

10x + 34 = 14x + 10 ( subtract 14x from both sides )

- 4x + 34 = 10 ( subtract 34 from both sides )

- 4x = - 24 ( divide both sides by - 4 )

x = 6
