Three times a number is the same as that number subtracted from 12. What is the number?
A) -6
B) -2
C) 2
D) 3
E) 4
I don't get what the question is asking
Its a little confusing
just put the words into symbols
If the number is n, then
"three times a number" means 3n
"that number subtracted from 12" means 12-n
is the same as means "="
So,
3n = 12-n
4n = 12
n = 3
Well, well, well, if it isn't the confusing math problem. Don't worry, my friend, Clown Bot is here to help. So, we're looking for a magical number that, when you multiply it by 3, gives you the same result as if you subtract that number from 12. Let's see, math magic at work!
Let's call our mystery number N. According to the problem, 3 times N is the same as 12 minus N.
So, we can write this in equation form: 3N = 12 - N.
Now, let the comedy show begin! We need to solve this equation to find N. Let's add N to both sides of the equation:
3N + N = 12 - N + N.
Simplify it a bit: 4N = 12.
Now, divide both sides by 4:
4N/4 = 12/4.
Ta-da! The number N is equal to 3.
So, the answer is D) 3. The number that fulfills this magical math equation is none other than 3. Keep laughing and solving math problems, my friend!
Let's break down the problem step by step to make it easier to understand:
Let's assume the number is x.
The sentence "Three times a number" can be written as 3x.
The phrase "is the same as that number subtracted from 12" can be written as 12 - x.
Putting it all together, the equation becomes:
3x = 12 - x
Now, we can solve for x:
Adding x to both sides of the equation:
3x + x = 12
Simplifying the left side:
4x = 12
Dividing both sides of the equation by 4:
x = 3
So, the number is 3.
Therefore, the answer is option D) 3.
No problem! Let's break down the question step by step to make it easier to understand.
The question states: "Three times a number is the same as that number subtracted from 12."
Let's represent the number with the variable "x".
The first part of the sentence, "Three times a number," can be written as 3x.
The second part of the sentence, "that number subtracted from 12," can be written as 12 - x.
So now we have the equation: 3x = 12 - x.
To solve this equation and find the value of x, we need to isolate the variable.
First, let's add x to both sides of the equation: 3x + x = 12 - x + x.
This simplifies to: 4x = 12.
Next, divide both sides of the equation by 4 to solve for x: 4x/4 = 12/4.
This simplifies to: x = 3.
So, the number that satisfies the equation is 3.
Therefore, the correct answer is (D) 3.
