What’s the value of b when x = 12

b =
2x2(x - 5)/
10x

Answer:

1/2

Step-by-step explanation:

6 - 4(0) = 6 (incorrect answer)

6 - 4(1/2) = 4 (correct answer)

6 - 4(2) = -2 (incorrect answer)

6 - 4(4) = -10 (incorrect answer)

Step-by-step explanation:

When a triangle is rotated 180° clockwise or anti clockwise both the x and y value will attain the opposite sign example:

(a,b) will be (-a,-b)

(1,-3)will be (-1,3)

Answer:

36 dollars per person and they all will pay 2 dollars each the large group will hit a wall

Answer:

Aksohia has $146 and Komley has $106

Step-by-step explanation:

The computation of the amount does each one have is shown below:

Let us assume Akoshia money be x

And, komley money be y

x>y

x - 20 = y + 20

x - y = 40

x = 40 + y.........(i)

2(y - 22) = x + 22

2y - 44 = x + 22

Now put the value of x in the above equation

2y - 44 = 40 + y + 22

2y - 44 = 62 + y

y = 62 + 44

= 106

And, x = 40 + 106

= 146

Answer:

75.

Step-by-step explanation:

100÷4= 25

25×3= 75

75/100

Answer:

75

Step-by-step explanation:

4 x 25 = 100

3 x 25 = 75

or

100/4 = 25

25 x 3 = 75

Answer:

The slope is 0

Step-by-step explanation:

There is no change in y values making the slope have a value of 0

Answer:

m = 0

Step-by-step explanation:

(5,0) and (6,0) would form a horizontal line.

All horizontal lines have a slope of zero.

Therefore, the slope of the line between (5,0) and (6,0) is 0.

Hope this helps.

Answer:

the ending balance is $531.51

Step-by-step explanation:

The computation of the ending balance is shown below:

= Opening balance + all deposits - all withdrawls

= $500 + $100 + $250 + $300 - $400.32 - $100 - $55.55 - $62.62

= $531.51

hence, the ending balance is $531.51

Answer:

6.16 miles

Step-by-step explanation:

When solving word problems like these, I like to start by drawing a picture.

So, Glera starts at her home and moves north by 5.8 miles. Then, she walks west by 2.1 miles to the library. The problem wants you to find the distance from her home to the library.

I've attached a drawing I made to help me visualize the problem. The distance from her home to the library is the hypotenuse of the triangle. To solve for it, you would use the equation [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex].

a and b are the sides of the triangle, and c is the hypotenuse.

[tex]5.8^{2}[/tex]  + [tex]2.1^{2}[/tex] = [tex]c^{2}[/tex]

33.64 + 4.41 = [tex]c^{2}[/tex]

38.05 = [tex]c^{2}[/tex]

To find c, you would take the square root of 38.05, which is about 6.16 if you use a calculator.

So, the distance from her home to the library is 6.16 miles!

Answer:

11 is the answer

Step-by-step explanation:

Answer:

11

Step-by-step explanation:

to find one of the addend

subtract another one of the addend by the sum

eg : 9 + __= 20

20 - 9 = 11

now we can check

9 + 11 = 20

Answer:

equation: 36000 + 4000x = 51000 + 1500x

value of x: 6

Step-by-step explanation:

Marshall:

36000 + 4000x

Jim:

51000 + 1500x

36000 + 4000x = 51000 + 1500x

360 + 40x = 510 + 15x

25x = 150

x = 6

Answer:

equation: 36000 + 4000x = 51000 + 1500x

9 stops * 2 miles = 18 miles on the subway

add the 188 miles traveled by train

188 + 18 = 206 miles

Answer:

35 times, or D

Step-by-step explanation:

A bag contains 5 red marbles, 6 blue marbles, 3 green marbles, 4 black marbles, and 2 yellow marbles. A marble will be drawn from the bag and replaced 100 times. What is a reasonable prediction for the number of times a green or black marble will be drawn?

A quick lesson on probability:

The probability of an event is: (the number of ways what you want can happen) / (total number of outcomes possible). For example, in a coin flip, there is 1 way to get heads, and 2 possible outcomes. Thus, the possiblity  of flipping a coin and getting heads is:

(1 way to get heads) / (2 possible outcomes) = 1/2

Then, if we were to flip the coin 100 times, we would expect about 1/2 of the times to be heads, so we should expect heads 50 times.  

On to the problem.

There are 3 green marbles and 4 black marbles, so there are 7 ways to draw a green or black marble.

Then, there are 5 + 6 + 3 + 4 + 2 = 20 possible outcomes.

Using the formula to find the probability, substitute the values we just found.

(the number of ways what you want can happen) / (total number of outcomes possible) =

(7 ways to draw a green or black marble) / (20 marbles that can be drawn) = 7/20 chance of getting a green or black marble.

Then, because there is a 7/20 chance of getting what we want, and there are 100 draws, we can say that an we should get green or black

7/20 * 100 = 35 times, or D

Answer:

20

Step-by-step explanation:

3x+50=6x-10 (vertically opposite angles)

50+10=6x-3x

60=3x

60/3=x

x=20

Answer:

x = 20

Step-by-step explanation:

6x - 10 = 3x + 50       {Vertically opposite angles}

6x        = 3x + 50 + 10     {Combine like terms}

    6x    = 3x + 60        {Subtract 3x from both sides}

6x -3x  = 60

     3x = 60         {Divide both sides by 3}      

        x = 60/3

x = 20
