Answer:
The answer is C
Sn=3(1-1/2^n)
Step-by-step explanation:
The correct equation to solve for x would be 12x - 19 + 4x + 1 = 180
Answer: 1700.00
Step-by-step explanation: Maybe, maybe not.
The solution 349 is given, and its number 3, 4 and 9 determine how many times 13 can be subtracted:
The first subtraction is 3x13 (x100) = 3900
The second subtraction is 4x13 (x10) = 520
The third subtraction is 6x13 = 78
So the answer is 520, which is also what you get when you subtract 78 from 598 of course.
