How can you add eight 6s together so that the total adds up to 750?

5

Step-by-step explanation:

We've used five 6's and have three left. Add each remaining 6 to the sum one at a time. All eight 6's have been used and totaled 750. When 12 is added to 8 times a certain number, the result is equal to subtracting 4 from 12 times the number.
