To make 30, you can add various pairs of numbers together. For example, adding 10 to 20 will give you 30, or adding 15 to 15 will also result in 30. Essentially, any two numbers that sum to 30 can be used, such as 0 and 30, or 25 and 5.
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
The two numbers that multiply to -30 and add up to 13 are 15 and -2. When you multiply 15 and -2, you get -30, and when you add them together, you get 13.
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.

factors of 30 that add to 17 are 2 and 15
The correct answer is: 1000+40+1000+30+1000+20+1000+10 = 4100
Add 30 which becomes 2744 and its cube root is 14
The two numbers that multiply to -30 and add up to 13 are 15 and -2. When you multiply 15 and -2, you get -30, and when you add them together, you get 13.
