Answer:
B -9(9x-3)
Step-by-step explanation:
b/c -9(9x-3) means -9×9x-(-3)
= -81x+27
if you say why -(-3) is +27, I will say b/c negative times negetive it give us positive. and if you they why we don't add -81x and 27, I will say b/c they are not like terms.
like terms : are terms with the same variable and same exponent.
example:2x and 3x,5xy and 9yx and etc....

Answer:
2/3
Step-by-step explanation:
To find the probability, you first have to add up the total number of marbles in the bag.
3+4+9+5=21
Next you find the probability of getting a yellow:
9/21
Then you find the probability of getting a green:
5/21
And since the problem says "yellow <em>or</em> green" we will add the two together
9/21 + 5/21 = 14/21 = 2/3

the answer is C (18:30)
Step-by-step explanation:
Each set of ratio in the table in simplest form is 3:5, and so is C.
6×3=18
6×5=30
So, 18:30 in simplest form is 3:5
Hope this helps!
X=4 , I believe this is the right answer
