What two digit number is three times the sum of its digits?
If a number with two digits is equal to four times the sum of its digits the number formed by reversing the order of the digits is 27 greater than the given number what is the number?
27 2+7=9 9x3=27
What is the number if there is a 4 digits number and no number is repeated The digit in the tens place is three times the digit in the thousand place. The sum of the digits in the number is 27?
3897 7 is in ones place 9 is in tens place (and is three times the number in thousands place) 8 is in the hundreds place 3 is in the thousands plac…e 7+9+8+3=27
153 = 13 + 53 + 33 Also: 370 = 33 + 73 + 03 371 = 33 + 73 + 13 407 = 43 + 03 + 73 See Related Links See the Related Links for "Exponentia…ted digit sums" to the bottom for more...
18 1+8=9 9x2=18
1+2+3=6 1x2x3=6 123
A two digit number is 3 times the sum of each digit If 45 is added to number the digits are reversed Find the number.?
That can be solved by treating the digits of the number as two separate variables, and then expressing the question as an equation: 10A + B = 3AB 3AB - 10A - B = 0 … A(3B - 10) - B = 0 A = B/(3B - 10) Now, we know that A and B must both be positive single digit numbers (otherwise, our first equation wouldn't fit the problem). That means "3B - 10" must give us a positive (in order to get that positive result). Because of that, we can see that B must be greater than or equal to 4. So let's try plugging in some values: if B = 4: A = 4/(12 - 10) = 2 if B = 5: A = 5/(15 - 10) = 4/5 As B goes up, A will get smaller and smaller. Since it is already a fraction, we know that the first answer is the only one. The answer then is 24.
Four times the sum of the digits of a two-digit number is equal to the number if the digits are reversed the resulting number is 27 greater than the original number what is the number?
The number is 36
that doesn't make a whole lot of sense, cuz the only digit of six is 6, so, if I'm interpreting this question correctly, the answer would just be 36. no, i actually think it…s 54.
A two digit number is five times the sum of the digits if 9 is added to the number the digits are reversed find the number?
There are 7 possible answers: 39, 48, 57, 66, 75, 84, 93. Answer can't include a 0,1 or 2, since the other digit will need to have a value greater than 9.
The tenths digit of a two-digit number is 3 more than the units' digit. The number is 8 more than six times the sum of the digits. Find the number.?
74 Let a1 represent the tens digit and ao represent the unit digit. From the problem, we have two equations: 10a1+ao = 8+6(a1+ao) a1=3+ao Substitute a1from the second equati…on into the first equation and solve for a0: 10(3+ao)+ao = 8+6((3+ao)+ao) 30+10ao+ao = 8+18+6ao+6ao 30+11ao = 26+12ao a0=4 Substituting this back into the second equation, we get: a1=3+4=7
The tens digit of a two-digit number is 2 more than the units digit. the number is 4 more than 6 times the sum of the digits. find the number.?
Call your number 10x + y. x = y + 2 and 10x + y = 4 + 6(x + y) Substitute y + 2 for x: 10(y + 2) + y = 4 + 6((y + 2) + y) This simplifies to 10y + 20 + y = 4 + 6y + 12 + 6y, i…e 20 - 16 = 12y - 11y so y = 4 and x = 6 Your number is 64, which is indeed 4 more than the sum of its digits.
What is the sum of all the positive two-digit integers where one of the digits is three times the other?
31 + 62 + 93 + 13 + 26 + 39 = 264
