28.964 and 1.036
The factor pairs of 30 are (30,1)(15,2)(10,3)(6,5) None of them add up to 20.
13 add something equals 30 = 43
It takes 30 twos to add up to 60. ( You discover this by dividing 60 by 2. )
It is impossible for three prime numbers less than 30 to add up to 1955. After all, 30+30+30 is only 90.

Quite a lot: 199 minus 30 is 169.
13 & 17
The factor pairs of 30 are (30,1)(15,2)(10,3)(6,5) None of them add up to 20.
One way is to multiply 3 and 7 in order to get 21 and then add 9 to 21 in order to get 30.
The lowest number you could add to make it divisible by 10, 2, and 5 would be 7. 23 + 7 = 30 30/10 = 3 30/2 = 15 30/5 = 6 Also, technically, you could add (-3) to make 20. 23 + (-3) = 20 20/10 = 2 20/2 = 10 20/5 = 4 Basically, you could add any number to 23 that would get a multiple of 10, since 2 and 5 are both factors of 10 to begin with.
60
factors of 30 that add to 17 are 2 and 15
13 add something equals 30 = 43
The correct answer is: 1000+40+1000+30+1000+20+1000+10 = 4100
Add 30 which becomes 2744 and its cube root is 14
It takes 30 twos to add up to 60. ( You discover this by dividing 60 by 2. )
