10 + 15 = 25. the tens digit of 25 is 2
456, because they are consecutive, 4+5+6 is equal to 15, which is smaller than 20 but larger than 10, and 5 (which is in the tens place) is odd. :)

If the sum of the digits in a two-digit number is 15, and the number is 6 more than 15 times the units digit, the number is 96. Let A and B be the digits. (A is the tens digit and B is the units digit) A + B = 15, therefore A = 15 - B 10A + B = 15B + 6Substituting for A, and solving for B...10(15 - B) + B = 15B + 6150 - 10B + B = 15B + 6150 - 9B = 15B + 6144 - 9B = 15B144 = 24BB = 6 Back substitute B into first equation and solve for A...A + 6 = 15A = 9 Therefore, the digits are 9 and 6, so the number is 96.
The number with 15 tens and 12 ones can be calculated by multiplying the number of tens by 10 and adding the number of ones. So, 15 tens is 150 (15 x 10) and adding 12 ones gives you 150 + 12 = 162. Therefore, the number is 162.

27. Let the first (tens) digit be x. Then, since the units digit is the tens digit plus 5, the second (units) digit is (x + 5) and the number is: 10x + (x + 5) = 11x + 5. And 3 times the sums of its digits is: 3(x + (x + 5)) = 3(2x + 5) = 6x + 15 But this is equal to the number, so: 11x + 5 = 6x + 15 ⇒ 5x = 10 ⇒ x = 2 ⇒ (x + 5) = (2 + 5) = 7 So the number is 27. Checking: 3 x (2 + 7) = 3 x 9 = 27
If the sum of the digits in a two-digit number is 15, and the number is 6 more than 15 times the units digit, the number is 96. Let A and B be the digits. (A is the tens digit and B is the units digit) A + B = 15, therefore A = 15 - B 10A + B = 15B + 6Substituting for A, and solving for B...10(15 - B) + B = 15B + 6150 - 10B + B = 15B + 6150 - 9B = 15B + 6144 - 9B = 15B144 = 24BB = 6 Back substitute B into first equation and solve for A...A + 6 = 15A = 9 Therefore, the digits are 9 and 6, so the number is 96.
The expanded form of 15 is 10 + 5. In expanded form, a number is broken down into its constituent parts based on its place value. Here, the digit 1 represents 10 (tens) and the digit 5 represents 5 (ones).

I love these: T = tens place or first digit. U = ones place, units place, or second digit. 10T+U is the first number T+U=15 = T=15-U 10U+T is the number with the digits switched. 10U+T=10T+U+9 10U+15-U=10(15-U)+U+9 9U+15=150-10U+U+9 9U+15=159-9U 18U=144 U=8 T=15-8 T=7
150/10=15
The number with 15 tens and 12 ones can be calculated by multiplying the number of tens by 10 and adding the number of ones. So, 15 tens is 150 (15 x 10) and adding 12 ones gives you 150 + 12 = 162. Therefore, the number is 162.
