is π11 a real number?​

Answer:

3/11

There are 11 possibilities and only 3 are even and less than 7.

Answer:

First, set x equal to .93

x=.939393939393...

Then, since the repeating is by two digits, let's multiply x by 100

This would make 100x=93.9393939393...

Now, we can subtract 100x−x

This would leave us with 99x=93 because the repeating digits cancel out.

This looks much easier now right?

Just divide the 99 and isolate the x to get x=9399

Get the simplified fraction, and the final answer is x=3133

Answer:

Step-by-step explanation:

-3≤ 6x - 9                 Add 9 to both sides

-3 + 9 ≤ 6x               Combine left

6 ≤ 6x                       Divide by 6

6/6 ≤ 6x/6

1 ≤ x

6x - 9 < 39               Add 9 to both sides

6x < 39 + 9              Combine

6x < 48                     Divide by 6

6x/6 < 48/6

x < 8

So the inequality is

1 ≤ x < 8

I think that is what you want. You have to express it as a combined inequality.

or equivalently

[tex]8\cdot m\cdot n[/tex]

We often write variable side-byside without the multiplication sign in algebra. It also applies to terms with indices. For instance,

[tex]\text{We write }a^2b^3c^4\text{ and mean }a^2\times b^3\times c^4[/tex]

We may, often also add a dot at the middle of both terms as another version of multiplication sign for better readability if the terms are more complicated, for instance

[tex]a\cdot b\cdot c[/tex]

and

[tex]\frac ab\cdot \sqrt{\frac{d^4}{b^9}}\cdot\pi[/tex]

1. How to Solve using Algebra

Make both equations into "y =" format.

Set them equal to each other.

Simplify into "= 0" format (like a standard Quadratic Equation)

Solve the Quadratic Equation!

Use the linear equation to calculate matching "y" values, so we get (x,y) points as answers.

Algebraic method is more easy to do

2. linear functions have constant first differences. quadratic functions have constant second differences. exponential functions have a constant ratio.

    To solve this problem form the system of equations as per statements given in the question then get the answer by solving them.

    Number of bushes in garden one were 55 and in second garden 11 originally.

   Let the number of raspberry bushes in one garden = x

And the number of raspberry bushes in second garden = y

So the equation for the given statement will be,

x = 5y -------(1)

Therefore, equation for this statement will be,

(x - 22) = (y + 22)

x - y = 22 + 22

x - y = 44 ------(2)

Substitute the value of x from equation (1) to equation (2)

5y - y = 44

4y = 44

y = 11

Substitute the value of 'y' in equation (1),

x = 5(11)

x = 55

                   Therefore, Number of bushes in garden one were 55 and in second garden 11 originally.

Answer:

Step-by-step explanation:

So, to go about your question, we must first ask, how many hours a week is being worked?

In this problem, that is 9 hours per week.

Next, we must question how much per week is made

That is $92 per week

Finally, we must determine if the allowance is occuring many times in the week or just once.

In this problem, that is only occuring once for the week.

So, the equation we must setup is 9x +20 =92.

To solve the equation, we need to subtract 20 on both sides to isolate the variable, x.

9x+20=92

     -20     -20

Now our equation is

9x=72

Now, to finally get x by itself or to isolate x, you should divide 9 on both sides to cancel out the 9 being multiplied by the x.

9x=72

9     9

x=8 because of 72/9 is equal to 8.

I hope this helps, and I will answer any questions you have.

Answer:

1/10

Step-by-step explanation:

8 black marbles, 5 white marbles and 12 red marbles = 25 marbles

P(red) = red/total = 12/25

Remove the marble

8 black marbles, 5 white marbles and 11 red marbles = 24 marbles

P(white) = white/total = 5/24

P(red, remove,white) = 12/25 * 5/24

                                   =12/24 * 5/25

                                   =1/2 * 1/5

                                   =1/10

Step-by-step explanation:

Total balls = 12 + 5 + 8 = 25 marbles

Probability of getting white marbles = 5/24

Probability of red marbles = 12/24 = 1/2

Now

Probability = 1/2 × 5/24 + 1

Probability = 1/2 × 5/25

Probability = 5/50

Probability = ⅒
