3:8 can also be written as 3/8

12:32 can also be written as 12/32

\frac{12}{32} = \frac{3\times 4}{8\times 4} = \frac{3}{8}

So thus 3:8 is equivalnt to 12:32

Dwayne plays five games of rock-paper-scissors. In order to seem unpredictable, he never chooses the same move (rock, paper, or
Andreyy89

Answer:

48

Step-by-step explanation:

First, in this problem, you would assume that there are five numbers to multiply since Dwayne played 5 games.  

 

                                                                                       

 

In the first blank, he could choose any move, and there are three, rock, paper, and scissors. In the first blank, you would put 3. Then, since you already picked one, you can't repeat it, so you would end up with 2 for the second blank. Continuing with the next blanks, the third, fourth, and fifth spaces would be 2 choices because you cannot have the one choice you chose previously. In the end, the blanks would look somewhat like this:

 

3    2    2    2    2

 

And you would multiply all the numbers.

 

3  x  2  x  2  x  2  x  2

                                                                  = 6 x 8

                                                                  = 48

What is the equation in point-slope form of a line that passes through the points (7, −8) and (−4, 6) ?
stiks02 [169]

Hello from MrBillDoesMath!


Answer: y - (-8) =  (-14/11) (x -7)      or    y + 8 = (-14/11) (x-7)


Steps:

Let's call  point  (7, -8)  (x1,y1) and point (-4,6)  (x2,y2). The point slope equation of a line through (x1, y1) is  

y- y1 = m(x-x1)


where "m" is the slope of the non-vertical line. Recall that m is rise/run or

m  = (y2- y1)/(x2-x1).

In our case

m = (6 - (-8))/( -4 - 7)  =  (6 + 8)/ (-11)    = - 14/11

The point-slope equation becomes

y - (-8) =  (-14/11) (x -7)

This can be rewritten as y + 8 = (-14/11) (x-7)

As a final check,  you should verify that this equation passes through the original points using substitution!

Regards, MrB.

I need some help. Can someone assist me with this?​
Y_Kistochka [10]

Answer:

x = 12

WN = 28

Step-by-step explanation:

SO = WN and SO = 2WI

3x - 8 = 2(x + 2)

3x - 8 = 2x + 4

3x - 2x = 4 + 8

x = 12 now replace x with 12 in the first equation given

3x - 8 = 3×12 - 8

36 - 8 = 28
