K - ( -3 ) = 12 how to solve⬆

K - (-3) = 12   When you subtract a negative number, it's the same as adding that                      number. So, your first step will be to cancel out the double                                    negative.
  k + 3 = 12   Next, subtract 3 from both sides of the equation to isolate k.
        k = 9

What is the length of BC?​
ELEN [110]

Answer:

24

Step-by-step explanation:

  • 3x - 15 = x + 33 [sides opposite congruent angles in a triangle are congruent]
  • 2x - 15 = 33 [subtract x from both sides]
  • 2x = 48 [add 15 to both sides]
  • x = 24 [divide both sides by 2]
  • BC = 24 [BC = x]

PLEASE HELP ASAP! DUE SOON PLEASE SHOW YOUR WORK
viktelen [127]

Answer:

So for the first one the first ting u have to do is FLIP the equation so---> X-12=y

Then you have to add 12 to BOTH sides----> x-12+12=y+12

<u><em>So your answer for X ----> x=y+12</em></u>

<u><em>For Y on the first equation it is--->y=x-12</em></u>      (Just flipped and the sign changed)

For the second equation we are gonna solve for Y first.

The first thing u want to do is divide both sides by -3 so it will look like this

-3y/-3    =   2x/+36/-3

<u><em>So Y will equal-----> -2/3x- 12</em></u>

Now we are going to do the X part

So fist FLIP the equation---->      2x+36=  -3y

The add -36 to both sides-----> 2x+36+-36=-3y+-36

Last step you have to divide both sides by 2

So that would be----> 2x/2= -3y-3

<u><em>Your final result will be----> x=-3/2y-18</em></u>

I hope this helped you out (:::::::

12 balls numbered 1 through 12 are placed in a bin. In how many ways can 3 balls be drawn, in order, from the bin, if each ball
Iteru [2.4K]

Answer:

1320

Step-by-step explanation:

There are three "spots" for balls.

__ __ __

For the first "spot," and without replacement, meaning we don't put the balls back, there are 12 choices.

12 __ __

But for the next spot, there are only 11 choices. And for the next, there are only 10!

12 11 10

Since these are independent events, we multiply them together.

12 x 11 x 10 = 1320

There are 1320 possibilities!

How could we do it on the calculator, much faster? The question says "in order," so we know it's a <em>permutation,</em> not a <em>combination.</em> This is the nPr button on the calculator (math -> prb -> 2). Just type in 12 nPr 3 and you get the same answer, 1320.
