Do some one know the answer  

54/56 in simplest form is 27/28.

Technically neither and at the same time both. 0 is not a real number so the fraction 0/0 is 0 and undefined. Also you have never shot so you have never missed or made it.

-3(2k-6)=12     divide both sides by -3

2k - 6 = -4        add 6 to both sides

2k = 2               divide both sides by 2

k = 1

Yep.....

On your second trip, you pay $37.50 for two more pairs of sweatpants...so...they must be $18.75 each

And (85.50 - 37.50) / 3  gives the price of each sweatshirt = $16

1/4 = 0.25

The expression "y<6" is called an inequality. You know that if it were to say "y=6", then y is exactly 6 and nothing else. "y<6" is similar, but instead means that y is less than 6. It's not giving you a specific value for y; instead, it's simply saying that y could be anything less than 6. It could be 3, it could be -1982347, it could be 1.23456789012345678901234567890 repeating six thousand times; anything just as long as it's under six. It could even be 5.9999999999999999999999999999999 -- even that is less than six (if only by 0.0000000000000000000000000000001). You can't simplify it any more than it is.

9 plus 10 equals 21 when you factor them hahaha

The answer is "undefined"

To see why....note that

0 / 0 = a      but what's "a" ???     ...it could be anything ...because multiplying "a" by the denominator of 0, we get the numerator 0......but since 0 times anything = 0, then "a" could be anything.....thus it's undefined...!!!

2m*9=9     divide both sids by 9

2m =1       divide both sides by 2

m = 1/2

6x-9-4x=5     simpllify on the left side

5x - 9 = 5     add 9 to both sides

5x = 14        divide both sides by 5

x = 14/5

the answer is 0 du

I dont't know plese help me on this question

ou yolo it.

$${\mathtt{9}}{\mathtt{\,\small\textbf+\,}}{\mathtt{10}} = {\mathtt{21}} = \tiny\text{Error: }$$

(k - 1) / 5  =  12

First:  multiply both sides by 5:

--->   5 · (k - 1) / 5  =  12 · 5

--->   k - 1  =  60

Now, add 1 to both sides:

--->   k  =  61

y=−2x+12ˏy=2x+44    I assume you want to solve this system...

Set the "y's" equal.....so we have....

-2x + 12 =2x + 44    add 2x to both sides.....subtract 44 from both sides

-32 = 4x      divide both sides by 4

-8 = x    and substituting this into either equation, we can find y

So

y = 2(-8) + 44  = -16 + 44  = 28

And the solution set is (-8, 28)

A bar notation means one of two things:

1)  If you have 7.263 with a bar above the 63:  this means that the 63 is repeated forever; 7.2636363636363...

2) If you have 2.2 - 1.16 with a bar above the whole expression:  this means the same thing as if you had parentheses around the expression; it means this:  (2.2 - 1.16)
