Answer:
72
Step-by-step explanation:
(9+9+7^2)-4+9
(9+9+49)-4+9
67-4+9=72
I believe this is correct.
<h3>Answer:</h3>
33
<h3>Explanation:</h3>
The repeating digits of the sum will have a cycle of length 6 (the LCM of 2 and 3). There will be 3 cycles of the 2-digit repeat, and 2 cycles of the 3-digit repeat.
The sum of digits of the cycle of interest is the sum of the digits in 3 cycles of "12" and 2 cycles of "345", thus 3·(1+2) +2(3+4+5) = 9+24 = 33.

<em>Another approach</em>
You can look at the sum on a per-digit basis. The 2-digit repeat {12} has a sum of 1+2=3, or 3/2 on a per-digit basis. The 3-digit repeat {345} has a sum of 12, or 12/3=4 on a per-digit basis. The sum of the two repeating decimals will have a sum per digit of 3/2 + 4 = 5 1/2. The 6 repeating digits will then have a sum of 6×(5 1/2) = 33.
Answer:
The answer is 63.5
Step-by-step explanation:
9.3(3)+8.9(4)
= 27.9 + 35.6
= 63.5
You can write 57,467/1,000
Well it depends what 'v' stands for
well all you need to do is replace the v with the number it stands for. For example if v=2 then the expression would be 4.2(2) - 5 - 6.5(2)
Then you use the order of operations. first you multiply
8.4 - 5 - 13
then you subtract from left to right
8.4 - 5 = 3.4
3.4 - 13 = -13 - 3.4 = -9.4
So IF v=2 (I used 2 as an example, V might not = 2 in your case) then the
answer will be -9.4
I hope this helped you :3
