I estimated the answer to be 18,000
Without estimation the answer would be 18,109
You're looking for c, so you want to isolate it or get it by itself. To get rid of the /3 you multiply since the opposite of division is multiplication and to get rid of it, you do the opposite (like -9 you would add 9 to get it to 0). Now you are left with -19+c = 24 (the 24 is 8*3 because what you do to one side you do to the other. Now you get c by itself so you add 19 to both sides which leaves you with C= 43. Sorry if this was confusing!
B because if you take it it would be b
The correct answer is a (8^3) because you write out 8 being multiplied 3 times, which is the correct answer
