What is 513 + _ + 130 = 764? what is the missing number and can u pls do a explantation

121

Step-by-step explanation:

The missing number is 121. I got this by doing 764-130-513=121. You would do this because you are trying to find the number that would allow 130 and 513 to add up to 764.

Another way to look at this problem is 513+130= 643

764-643=121

In conclusion, 513+121+130=764

the answer will be 121

Step-by-step explanation:

because 513 + 130= 643 then 121 + 643 = 764
