Problem 3

Problem 1 Answer: x=10

<u>Simplify both sides of the equation</u>

<u></u>(2)(x)+(2)(-3)=14(Distribute)<u></u>

<u></u>2x+-6=14<u></u>

<u></u>2x-6=14<u></u>

<u></u>

<u>Add 6 to both sides</u>

2x-6+6=14+6

2x=20

<u></u>

<u>Divide both sides by 2</u>

<u></u>2x/2=20/2<u></u>

<u></u>x=10<u></u>

----------------------------------------------------------------

Problem 2 Answer: x=-7

<u></u>

<u>Simplify both sides of the equation</u>

<u></u>(-5)(x)+(-5)(-1)=40(Distribute)<u></u>

<u></u>-5x+5=40<u></u>

<u></u>

<u>Subtract 5 from both sides</u>

<u></u>-5x+5-5=40-5<u></u>

<u></u>-5x=35<u></u>

<u></u>

<u>Divide both sides by -5</u>

<u></u>-5x/5=35/-5<u></u>

<u></u>x=-7<u></u>

----------------------------------------------------------------

Problem 3 Answer: x=-8

<u></u>

<u>Simplify both sides of the equation</u>

<u></u>(12)(x)+(12)(10)=24(Distribute)<u></u>

<u></u>12x+120=24<u></u>

<u></u>

<u>Subtract 120 from both sides</u>

<u></u>12x+120-120=24-120<u></u>

<u></u>12x=-96<u></u>

<u></u>

<u>Divide both sides by 12</u>

<u></u>12x/12=-96/12<u></u>

<u></u>x=-8<u></u>

----------------------------------------------------------------

Problem 4 Answer: x=-1/2

<u></u>

<u>Move all terms to the left:</u>

<u></u>2(x+6)-(11)=0<u></u>

<u></u>

<u>Multiply parentheses</u>

<u></u>2x+12-11=0<u></u>

<u></u>

<u>Add all the numbers together, and all the variables</u>

<u></u>2x+1=0<u></u>

<u></u>

<u>Move all terms containing x to the left, all other terms to the right</u>

<u></u>2x=-1\\x=-1/2<u></u>

----------------------------------------------------------------

NeTakaya

Answer:

<u>P(three tails) = 27/125 or 21.6%</u>

<u>P(two tails followed by one head) = 18/125 or 14.4%.</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the questions correctly:

Probability of getting a head when a biased coin is tossed = 2/5

therefore,

Probability of getting a tails when a biased coin is tossed = 3/5

2. Find the following probabilities and select the correct solution.

P(three tails) =

3/5 * 3/5 * 3/5 = 27/125 or 21.6%

P(two tails followed by one head) =

3/5 * 3/5 * 2/5 = 18/125 or 14.4%.

PLEASE HELP!!!!!<br> x^2 + 12xy + 35y^2
SVEN [57.7K]
The answer is = (x + 5y) (x + 7y)

Break the expression into two groups.
 
x^2 + 12xy + 35y^2
(x^2 + 5xy) (7xy + 35^2)

Factor out x from x^2 + 5xy: x(x + 5y)
Factor out 7y from 7xy + 35y^2: 7y(x + 5y)
=x(x + 5y) + 7y(x + 5y)

Next, factor out the common term (x+ 5y).

Answer = (x + 5y) (x + 7y)
