l am two digit number. My tens digit is double of my ones digit .The sum of my digit is nine?
Let the digits be a, and b.
Your number is x.
x = 10 a + b
My tens digit is double of my ones digit means:
a = 2 b
Now:
The sum of my digit is nine means:
a + b = 9
Replace a with 2 b in this equation.
2 b + b = 9
3 b = 9
b = 9 / 3
b = 3
a = 2 b = 2 ∙ 3 = 6
x = 10 a + b
x = 10 ∙ 6 + 3 = 60 + 3 = 63
Your number is 63
Well, it seems like you're a real number riddle! Let's see if I can figure you out.
Since you mentioned that you're a two-digit number, let's call your tens digit "T" and your ones digit "O". According to your clues, T = 2O and T + O = 9.
If we substitute T with 2O in the second equation, we get 2O + O = 9. Combining like terms gives us 3O = 9. By dividing both sides by 3, we find O = 3.
Now that we know O is 3, we can substitute it back into the first equation to find T. T = 2(3) = 6.
So, putting it all together, you are the two-digit number 63! Ta-da!
To find the two-digit number that meets these conditions, we need to follow these steps:
Step 1: Let's assume the ones digit as "x".
Step 2: As per the condition, the tens digit is double the ones digit. So, the tens digit is "2x".
Step 3: The sum of the digits is nine. So, we can write the equation:
x + 2x = 9
Step 4: Simplifying the equation:
3x = 9
Step 5: Dividing both sides of the equation by 3:
x = 3
Step 6: Now, substitute the value of x back into the equation to find the tens digit:
2x = 2 * 3 = 6
Step 7: Therefore, the tens digit is 6 and the ones digit is 3, so the two-digit number is 63.
So, the two-digit number that meets the conditions is 63.
To find the two-digit number that meets these conditions, we need to follow a step-by-step approach.
Let's assume the tens digit is represented by the variable 'x' and the ones digit is represented by the variable 'y.'
Based on the given information:
1. The tens digit is double the ones digit: x = 2y
2. The sum of the digits is nine: x + y = 9
Now we can solve these equations simultaneously to find the values of 'x' and 'y.'
Step 1: Substitute the value of x from equation 1 into equation 2:
2y + y = 9
Simplifying the equation:
3y = 9
Step 2: Solve for y by dividing both sides of the equation by 3:
y = 9/3
y = 3
Step 3: Substitute the value of y back into the first equation to find the value of x:
x = 2y = 2*3 = 6
Therefore, the two-digit number is 63, where the tens digit (6) is twice the ones digit (3), and the sum of the digits is nine.
