Starts off at 7 ends at114688, subtract them, 114681. Now there are 8 terms so subtract 1 because you're starting from the beginning, that leaves 7. Now divide 114681/7=16,383 difference per point, Now 1st pt is 7 2nd is 16390 3rd is 32773 4th is 49156 5th is 65539 6th is 81922 7th is 98305 8th is 114688 Now add these= 458780

since it is 4 hours from 8:30 a.m. to 12:30 a.m. you put 4 into x.

25+15.75(4) = y

88 = y

What is the solution to the open sentence 18 = c + 6?
sveticcg [70]
This is very simple, all you have to do is subtract 18 and 6 and that would be 12, and now we have 12 as a POSSIBLE answer, lets check our work to be 100% correct so now try to add 12 and 6 and we get 18, so yay it made the equation true and since its true its right so that's the answer.

Answer: c = 12 so 18 = 12 + 6 is true.
