What is a fraction
In such a fraction, the value that appears above the horizontal line is referred to as the numerator.
In another word, the fraction is the division of the two numbers but the division is not wholly complete.
It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the brings together various.
In question, let's assume that the number is x then according to the question
(1/3)x = x - 12
x = 3x - 36
36 = 3x + x
36 = 4x
x = 18 hence, it will be correct.

Answers
There are 4 red marbles.
There are 7 blue marbles.
There are 5 green marbles.
There are 16 marbles in total.
a.
Answer = (probability of selecting a red marble)(probability of selecting a blue marble)
First, the probability of selecting a red marble.
Next, the probability of selecting a blue marble.
Multiply the probabilities together.
That is the probability for event a.
b.
Answer = (probability of selecting a red marble)(probability of selecting a blue marble)
First, the probability of selecting a red marble.
Next, the probability of selecting a blue marble WITH A RED MARBLE REMOVED.
Multiply the probabilities together.
That is the probability for event b.
c.
Obviously:
So the answer is no.

Answer:
5.4 x 10 ^ -5
Step-by-step explanation:
Answers
First you do everything in the parentheses.
2 times x= 2x
2 times -3=-6
Now you have 5 + 2x- 6
5 plus -6=-1
Now you have 2x-1=0
Add the -1 to both sides.
2x-1+1=0+1
Now simplify that to get: 2x=1
Now you divide each side by 2 to get x by itself.
So, x= 1/2
You must use the distributive property to get an answer.
So, 2(x-3), correct? Okay, so first you multiply 2 times x, which would give you:
2x
Then you multiply 2 times 3, which gives you 6.
So now, you have 5+2x-6 - (Basically, we just extended the problem.)
Then we just simplify, which gives you... (drumroll please...?) 2x-1.
Hope this helps!
