Answer:

Pretty sure it's 10

Answer:

×=7, pq=27, qr=20.

Step-by-step explanation:

(4x-1)+(3x-1)=47 therefore 7x-2=47 or 7x=49 and x=7, pq=4x-1=27, qr=3x-1=20.

Answer:

1/4 is the answer ........

Answer:

0.57

Step-by-step explanation:

Step 1: Count the total amount of squares

10 by 10 square, so 100 squares in total

Step 2: Count how many rows have been filled

5 rows of 10, so 50 out of 100, or 0.50

Step 3: Count the rest

7 out of 100, so 0.07

Step 4: Add

0.07 + 0.50 = 0.57

Answer:

0.57

Step-by-step explanation:

Hi :)

If a cell phone plan costs 30 per month and charges 15 cent per text message and 200 text messages were sent,

The base charge is 30 dollars, multiply 0.15 by 200

30 + (0.15 * 200)

30 + (30)

For this month,

$60

Hope this helps,

Answer:

Derek will buy 73 1/3 pounds of lunch meat to make 330 sandwiches

Step-by-step explanation:

People at the picnic = 300

For every 10 people 11 sandwiches will be eaten

Total sandwiches eaten by 300 people = 300/10 × 11

= 30*11

= 330 sandwiches

330 sandwiches will be eaten at the picnic

20 pounds of meat will make 90 sandwiches.

90/20 = 330/x

Cross product

90x = 330*20

90x = 6,600

Divide both sides by 90

x= 73 1/3

Derek will buy 73 1/3 pounds of lunch meat to make 330 sandwiches

73 1/3 pounds 330 sandwiches

Answer:

2x^3 - 10x^2 +12x

Step-by-step explanation:

p(x)= 2x^2 -4x

q(x) = x-3

(p•q)(x) = (2x^2 -4x) * ( x-3)

        FOIL

first 2x^2 *x = 2x^3

outer  2x^2 *-3 = -6x^2

inner -4x *x = -4x^2

last  -4x*-3 = 12x

Add together

2x^3 -6x^2 -4x^2 +12x

Combine like terms

2x^3 - 10x^2 +12x

Answer:

Step-by-step explanation:

p(x) =2x² - 4x

q(x) = x - 3

In order to find (p•q)(x) substitute q(x) into p(x) that's replace every x in p(x) by q(x)

That's

(p•q)(x) = 2( x - 3)² - 4( x - 3)

Expand the terms

That's

(p•q)(x) = 2( x² - 6x + 9) - 4x + 12

= 2x² - 12x + 18 - 4x + 12

Group like terms

(p•q)(x) = 2x² - 12x - 4x + 18 + 12

Simplify

We have the final answer as

(p•q)(x) = 2x² - 16x + 30

q = 3

r = -6

q - r = 3 - (-6) = 9

I would compute sqrt(1 + 160pi^2) first to get approximately 39.75093337

Add this to 1 and we have 40.75093337

Then divide over 2pi to get a final approximate result of 6.48571248

So x = 6.48571248 is one approximate solution

In short, I computed [tex]\frac{1+\sqrt{1+160\pi^2}}{2\pi}[/tex] only focusing on the plus for now.

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

If you were to compute [tex]\frac{1-\sqrt{1+160\pi^2}}{2\pi}[/tex] you should get roughly -6.167402596 as your other solution. Each solution can then be plugged into the original equation to check if you get 0 or not. You likely won't land exactly on 0 but you'll get close enough.

Answer:

x = 6.49

Step-by-step explanation:

1st is to calculate [tex]\sqrt{1 + 160 pi^2}[/tex] = 39.75 then add 1 = 40.75

2nd divide it by 2pi = 40.75/(2pi) = 6.49

therefore your x = 6.49

the equation would look like

   1 ± [tex]\sqrt{1 + 160 pi^2}[/tex]            1  ±  39.75

= --------------------------  =  ---------------- = 6.49

           2*pi                        6.28

Answer:

x = -1

Step-by-step explanation:

Step 1: Write out equation

-3x + 5 = 2x + 10

Step 2: Add 3x on both sides

5 = 5x + 10

Step 3: Subtract 10 on both sides

-5 = 5x

Step 4: Divide both sides by 5

-1 = x

Step 6: Rewrite

x = -1

Answer:

x = -1

Step-by-step explanation:

you want to move all the numbers with an x to one side and the ones without to the other so you get.

-5x=5

then you divide by 5 on both sides and get x = -1

Answer:

The first thing you need to do here is create an equation.

I've created it for you: 6x = 8x - 4

If you want to solve it, you have to move the like terms to one side so...

4 = 2x

and x = 2

The correct answer is C on Edge.

Step-by-step explanation:

Answer:

$895.20

Step-by-step explanation:

Answer: The answer is: it is a fifth degree binomial or 'quintic binomial'.

Step-by-step explanation:

Is the expression 3x^2-5x^3 a polynomial?

So, we have to know what polynomial means. A polynomial is... "an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables."

So let's take a look at this expression.

Does it consist of variables and coefficients? YES

Does it only involve operations of addition, subtraction, multiplication, and non-negative integer exponents of variables? YES

Therefore, it is a polynomial.

Now, we have to figure out what degree this polynomial is.

The degree of the polynomial is the degree of the monomial with the largest degree.

So the largest degree would be the 3rd degree, because it is, of course, the largest out of the two powers listed.

And also, keep in mind that this is a binomial (made up of two monomials).

Therefore, it is a fifth degree binomial or 'quintic binomial'.

Answer:

x = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Given

f(x) = [tex]\frac{x-4}{2x-3}[/tex]

The denominator cannot be zero as this would make f(x) undefined.

Equating the denominator to zero and solving gives the value that x cannot be and if the numerator is non zero for this value then it is a vertical asymptote.

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]

Thus x = [tex]\frac{3}{2}[/tex] is the vertical asymptote

Answer:

b= 322.8

Step-by-step explanation:

10.50a + 3.75b = 2071.50

10.50 (82) + 3.75b = 2071.50

861 + 3.75b = 2071.50

-861                -861

3.75b = 1210.5

/3.75     /3.75

b = 322.8

Answer: 1:10,000

Step-by-step explanation:

given data:

distance of the nearest star system = 100,000,000

distance to size ration of the sun earth system = 10,000

therefore;

100,000,000 / 10,000

= 10,000

The order of magnitude of the distance to size ratio of the Sun- Nearest Star system is about 1:10,000 times that of the Sun-Earth system.

Answer:

He used [tex]1\frac{7}{8}\ lb[/tex]

Step-by-step explanation:

Given

[tex]Total = 3\ lb[/tex]

[tex]Fraction = \frac{5}{8}[/tex] to make sauce

Required

Determine the number of pounds used

To solve this, we simply multiply the fraction of tomato used by the total;

[tex]Used = Fraction * Total[/tex]

[tex]Used = \frac{5}{8} * 3\ lb[/tex]

[tex]Used = \frac{5 * 3}{8}\ lb[/tex]

[tex]Used = \frac{15}{8}\ lb[/tex]

Convert to mixed number

[tex]Used = 1\frac{7}{8}\ lb[/tex]

Hence,

He used [tex]1\frac{7}{8}\ lb[/tex] out of the 3lb he bought

Answer:

8

Step-by-step explanation:

10 + 8 = 18

18 x 2 = 36

Answer:

So we know the sum of two numbers, let them be x and y, is equal to 36:

x + y = 36

And on of them, for example, y, is equal to 10:

x + 10 = 36

Now, the only thing we need to do is solving the equation to find x:

x + 10 = 36

We pass the 10 substracting to the right:

x = 36 - 10

And now, we substract:

x = 26

Now we know one number is 10 and the other is 26, so we can verify we have done all correctly

26 + 10 = 36 (TRUE)

Now we know we have done the exercise well.

Answer:

Hello! :) I hope I am correct!!

Step-by-step explanation:

The answer would be: x=9

(Below is how I got ‘x=9’)

Here are the steps to solve this problem/equation.

1. Simplify both sides to the equation.

⇒10x +-21=61

⇒10x -29=61

2. Now add 29 to both of the sides

⇒ (you will end up with: 10x=90

3. And finally you divide both sides by 10

⇒ so x=9

Hope this helps!
