Let the number be represented as ( x ). The expression for the sum of 10 times the number and 15 added to 11 times the same number can be written as ( 10x + (11x + 15) ). Simplifying this gives ( 21x + 15 ). Therefore, the sum is ( 21x + 15 ).
To find the least number that must be added to 308 to make it divisible by 19, we first divide 308 by 19. The division gives a quotient of 16 with a remainder of 4, since ( 19 \times 16 = 304 ). To make 308 divisible by 19, we need to add ( 19 - 4 = 15 ). Thus, the least number that must be added is 15.
4x - 4 = 3x + 114x - 3x = 11 + 4x = 15
22 out of 30 ... since 30 is twice as large as 15, the answer must be half of 22, or 11. Put another way, 22 and 30 are twice as large as 11 and 15. 11/15 = .733 = 22/30 If you like my answer, please recommend me as a contributor.
11 is prime.

24 this is how it breaks down -15 + x = 9 => x= 9 + 15 => x= 24
15 for example, but also any other number multiplied by 11 to which 4 is added. eg 11x12+4 = 136.
15 is a composite number. 11 is a prime number.

15
it is the number such that 15 added to negative 15=0
4x - 4 = 3x + 114x - 3x = 11 + 4x = 15
write the answer on the blank what number is 11 more than 15?______

Any rational number does.
