Let the number be x and if 9+2x = 15 then x equals 3
The number is 45. The sum of its digits i.e. 4+5=9 Five times the sum of its digits i.e. 5 times 9 which is 45
Assign the term "any number" the value "x" Therefore: 9x + 5x = x(9+5) = 14x Therefore the sum of any two numbers which are multiples of a number is the base number multiplied by the sun of the multipliers.
9(4+n)Nine times the sum of 4 and a number is an expression and can not be evaluated.
81 8+1=9 9*9=81

45

The number is 54. The sum of its digits is 5 + 4 = 9. 54/9 = 6.
20 5 times 4= 20 5+4=9
81
the answer is 9
9(4+n)Nine times the sum of 4 and a number is an expression and can not be evaluated.
81 8+1=9 9*9=81
Let the number be 'n' & '2n' , Since '2n' is twice as large as 'n'. Hence 2n + n = 27 3n = 28 Divide both sides by '3' n = 9 Hence 2n - 18 Verification 9 + 18 =27
Numbers are 9 and 2
