# What two digit number is three times the sum of its digits?

# What two digit number is 5 times the sum of its digits?

Answer: 45.
4 + 5 = 9 x 5 = 45

# What is the number of a two digit number that is four times the sum of its digits The tens digit is 3 less than the units digit?

36.
[1] b Ã¢ÂˆÂ’ 3 = a [2] 4(a + b) = 10a + b [3] 4a + 4b = 10a + b Substitute [1] (b Ã¢ÂˆÂ’ 3) for a in [3]: [4] 4(b Ã¢ÂˆÂ’ 3) + 4b = 10(b Ã¢ÂˆÂ’ 3) + b [5] 4b Ã¢Â…ˆÂ’ 12 +4b = 10b Ã¢ÂˆÂ’ 30 + b [6] 18 = 3b [7] 6 = b [8] 3 = a

# A number is three times the sum of its digit find the number?

Is this exactly how the problem was written?

# Two digit number is three more than 7 times the sum of it's digits?

If there are two digits than the first one is ten times its value. So as an algebraic equation we get 10A + B - 3 = 7(A x B) This can be simplified to 10A + B - 3 …= 7A + 7B and this reduces to 10A - 7A = 7B - B +3 or 3A =6B +3 A solution to this is 3(3) = 6(2) +3 Which would make the original equation 32 = 7(3+2)-3

# A two digit number is four times the sum of its digits?

Call the digits 'A' and 'B', so that the number is written: AB. 10A + B = 4 (A+B) 10A + B = 4A + 4B 6A = 3B 2A = B ---> any 2-digit number where the units digit is… twice the tens digit 12 or 24 or 36 or 48

# What is two digit number which is nine times the sum of its digits?

81 : 8 + 1 = 9, and 9 x 9 = 81. Here's how to figure: If the 2-digit number is ab,. then the number is equal to 10*a + b. And nine time the sum equals 9*(a + b). Set these… two equal and you have: .
9*a + 9*b = 10*a + b --> 8*b = a. Knowing that the digits must be in the range 1 through 9: 1 x 8 = 8, and 2 x 8 = 16, so the only possibility is a=8 and b=1.

# What is the sum of the two digit number?

The sum of the two digit number depends on what the number is for e.x. 27 + 32= 59. You get this by first adding the 7 and the 2 together, because if you would line the proble…m up and down the would be lined up directly below or above each other, getting an answer of nine. Then you add the 3 and the 2 together getting an answer of 5. To complete your results you will put the five in the front because it is the sum of 3 and 2 and they were both in the front and then you will write the 9 at the end because it is the sum of the 7 and the 2 and they were both at the end of the number.
