if the sum of three is six then it would be 30 right??

i think depends on wat sum of 3 is

The algebraic expression for the sum of 11 times 5 and three is 11s+3

The algebraic expression is 3(b+5).

because the number are the same /example2 times 3 equals 6. 3 times 2 equals 6

You mean : 7*(3+5)=7*8=56

(21/7) + (3 x 5) = 3 + 15 = 18

3 _ 18 3 _ 18

The sum of xy times 3 is equal to 3(xy).

That can be defined as 5(x + 3)

the sum of 3 times m and n

That number would be 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

If you mean -5 + (-3) then the sum of the two numbers is -8

20, because 15 divides by 5 is 3, And 3 times 8 is 24, And 24 minus four is 20.

five times the sum of a number and 8 is -15.

The two numbers that solve this problem are 5 and 15. The sum of 5 and 15 is equal to 20, and 15 is indeed 3 times 5.
