how do you write 2x simplified?

Answers

Answer 1

Answer:

Simplify the numerator with the sine expression by taking A = B = x and simplify the denominator using A = x and B = 2x. The resulting denominator will have sin (2x) and cos (2x) which you can write in terms of sin (x) and cos (x) using the expressions above.

The measures of the angles of a quadrilateral are 3:8:7:2 find the measure of each angle

Answers

Answer:

Angle 1=  54°

Angle 2= 144°

Angle 3 = 126°

Angle 4 = 36°

Step-by-step explanation:

We are given measures of the angles of a quadrilateral are 3:8:7:2

Let the common ratio = x

The angles will be:

Angle 1= 3x,

Angle 2= 8x,

Angle 3 =7x

Angle 4 =2x

We know that sum of all angles of quadrilateral = 360°

We can write as: [tex]3x+8x+7x+2x=360[/tex]

Solving to find x,

[tex]3x+8x+7x+2x=360\\20x=360\\x=\frac{360}{20}\\x=18[/tex]

We get value of x = 18

Now, finding angles:

Angle 1= 3x = 3(18) = 54°

Angle 2= 8x = 8(18) = 144°

Angle 3 =7x = 7(18) = 126°

Angle 4 =2x = 2(18) = 36°

Step-by-step explanation:

this is correct :)

Answer:

x=7

Step-by-step explanation:

-8x+4=-52

First remove the four by subtracting 4 from -52

-8x= -56

Then, you would want the variable (x) by itself, so you divide by -8 (Dividing a negative by a negative makes a positive)

x=7

To confirm this answer is right, plug in 7 as the variable and make sure you get -52

(-8*7)+4= (-52)

What is the value of x in the equation? 6(x +1) -5x = 8 + 2(x - 1) *

Answers

Answer:

x = 0

Step-by-step explanation:

6 ( x + 1 ) - 5x = 8 + 2 ( x - 1 )

6x + 6 - 5x = 8 + 2x - 2

-x = 0

x = 0

Answer:

x = 0

Step-by-step explanation:

First distribute both sides to simplify the equation

6(x +1) -5x = 8 + 2(x - 1)    =

6x + 6 - 5x = 8 + 2x - 2

Combine like terms

x + 6 = 6 + 2x

Subtract x from both sides

6 = 6 + x

Subtract 6 from both sides

0 = x

19,432÷x=48 Remainder 232 (Plz help its for my hw that's due tmrw)

Answers

Answer:

x = 404.83

Step-by-step explanation:

The given expression is :

19,432÷x=48 ...(1)

We need to find the value of x.

[tex]\dfrac{19,432}{x}=48[/tex]

Cross multiplying both sides,

[tex]19,432=48x[/tex]

Dividing both sides by 48

[tex]\dfrac{19,432}{48}=x\\\\x=404.83[/tex]

So, the value of x is 404.83.

Answer:

x = 400

Step-by-step explanation:

To find x, you first need to subtract the remainder from 19,432.

That equals 19,200. Then you need to do 19,200 divided by 48.

x = 400

Use differences to find a pattern in the sequence.

Answers

The 8th term of the pattern is 254.

Here the sequence is 9, 16, 29, 50, 81, 124, 181

By using differences we have :

  |___|  |___| |___|  |___|  |___|  |____|

                ↓          ↓         ↓          ↓

               +2        +2       +2        +2

Therefore to find the 8th value of the pattern

We will add 2 in 14

14 + 2 = 16

Now 16 should be added to 57

57 + 16 = 73

Now we will add 73 to the 181 we get

181 + 73 = 254

Therefore the 8th term of the pattern is 254 by using the difference.

Intuitively, the answer will be 4 - i, as the other numbers are too big to have a square as small as 17i.  Also, we know that  i will not be in the end result, which means that we should have a negative in the result as well.

First we convert into slope-intercept form | y = mx + b

[tex]-3y=-3-x[/tex]

Move x to another side and subtract. (Whenever you move to another side, the sign/operator will be opposite. From plus to minus and from multiply to divide.)

Then move -3 to divide (-3-x)

[tex]y=\frac{-3-x}{-3}[/tex]

Separate - [tex]y=\frac{-3}{-3}-\frac{x}{-3}[/tex]

| Negative dividing Negative equal positive |

[tex]y=\frac{3}{3}-(-\frac{x}{3})[/tex]   | When the denominator is negative, we can pull out from the denominator and convert into the middle of fraction. |

| Negative multiplying Negative equal positive |

[tex]y=1+\frac{x}{3}[/tex]

This is not fully slope-intercept form yet. We swap the position of 1 and x/3

[tex]y=\frac{x}{3}+1[/tex]

There we go. The slope-intercept form.

Now our job is to find the x-intercept and y-intercept. First, know what m and b represents in the equation y = mx + b first.

From y = mx + b | m represents slope | b represents the y-intercept. |

Our equation is [tex]y=\frac{x}{3}+1[/tex]

Our m or slope is 1/3 and our y-intercept is 1. So we don't need to find the y-intercept because we've already found it.

Now move to finding x-intercept.

Substitute y as we get -

[tex]0=\frac{x}{3}+1[/tex]

Now whenever there is a denominator, multiply the whole equation by the denominator itself. As our denominator in this equation is 3, so we multiply all whole equation by 3.

[tex]0(3)=\frac{x}{3}(3)+1(3)\\0=x+3 \\x=-3[/tex]

Our x-intercept is x = -3 and y-intercept is y = 1.

Check the graph out. Our answers can be only A and B considering the slope is positive. C and D choices have negative slope (m < 0).

However, the value of slope also affects the graph. If the slope has a lot of value, then the graph will head to y-axis.

But if the slope has a little value then the graph will head to x-axis instead.

After all, when converting to the slope-intercept form. We don't need to find the x-intercept right away, just one glance at the graph along with the equation and we are able to answer it.

Thus, the answer is B choice.

I know it is a long, boring explanation. But providing a quality answer is what I'm trying to do. I may not be able to explain that good or whatever. But with an explanation, I hope it will benefit you someday, after all. An explanation can help you in a test. Thanks for reading and I hope this helps you.

Worldwide, the proportion of babies who are boys is about 0.51 . Let the random variable X represent the number of boys in five children. Find the mean and standard deviation of this random variable.

Answers

Answer:

mean = 2.55

Standard deviation = 1.118

Step-by-step explanation:

Probability of babies who are boys

P = 0.51

Then we have q = 1-p

= 1-0.51

= 0.49

We have n = 5

We calculate the mean as:

np

= 0.51x5

= 2.55

Therefore mean = 2.55

The standard deviation

= √variance

= √npq

= √0.51x5x0.49

Gasoline costs 1.05 euro per liter in France. What is the price in dollars per​ gallon?

Answers

The price in dollars per gallon is 4.02 dollars per gallons.

How to find the price of gasoline in dollars per gallon?

Gasoline costs 1.05 euro per litre in France.

The first thing to do is to determine the equivalent amount of the same litre in dollar while in France.

Then, equate it the quantity of litres to gallons.

Hence,

1 euro = 1.01 dollars

1.05 euro = ?

cross multiply

price  = 1.05 × 1.01

price = 1.0605 dollars

1 litres = 0.264172 gallons

Therefore,

cost =  1.0605 /  0.264172

cost  = 4.01552442257 dollars per gallons

cost  = 4.02 dollars per gallons

Therefore, the price in dollars per gallon is 4.02 dollars per gallons.
