Answer:
d < 8
Step-by-step explanation: Obviously, you need to find out what D is. First you do the opposite of positive 4 to make it 0. You have to subtract 4, so you therefore subtract 4 from 52 as well, which is 48. Now you find out what 48/6 is to get the value of d which is < (less than) 8. Any d value less than 8 will give us a valid answer, however any d value more than 8 will give you an invalid answer.
