Answer:
5 - -3..... i think
Step-by-step explanation:
The answer is x=3.6 or 3 3/5.
First we convert the decimal answer to a fraction; 0.9 is read as "nine tenths," so the corresponding fraction is 9/10:
1 5/6 - (x - 7/12) + 2 1/12 = 9/10
Now we find a common denominator. The first thing that 6, 12 and 10 will all divide into is 60:
1 50/60 - (x - 35/60) + 2 5/60 = 54/60
Distributing the negative, we have:
1 50/60 - x + 35/60 + 2 5/60 = 54/60
Combining like terms, we have:
-x + 4 30/60 = 54/60
Subtracting 4 30/60 from each side, we have:
-x + 4 30/60 - 4 30/60 = 54/60 - 4 30/60
-x = -3 36/60
Divide both sides by -1:
-x/-1 = (-3 36/60)/-1
x = 3 36/60 = 3 3/5 = 3.6
Find 7% of 5000 students ?
Answer :
![5000 \times \frac{7}{100} = 350](https://tex.z-dn.net/?f=5000%20%5Ctimes%20%20%5Cfrac%7B7%7D%7B100%7D%20%20%3D%20350)
<u>So, 7% of 5000 students is 350 students.</u>

The expression that is used to calculate payments with compound interest has the following elements: An initial payment P0, a compound interest rate r, a period of time t and an income I. The formula has the following form:
![I = P_0 (1 + r) ^ t](https://tex.z-dn.net/?f=I%20%3D%20P_0%20%281%20%2B%20r%29%20%5E%20t)
In this case we have an interest rate r = 0.08, t = 8 years, initial fee P0 = 850
So:
![I = 850 (1 + 0.08) ^ 8](https://tex.z-dn.net/?f=I%20%3D%20850%20%281%20%2B%200.08%29%20%5E%208)
I = $ 1573.29
Then, the amount obtained by interest is:
$ 1573.29 - $ 850 = $ 723.29
Answer:
Total amount = $ 1573.29
Amount of interest = $723.29
Answer:
Now, each student contributes= Rs 61 1/2= Rs 123/2 ( mixed fraction ).
Therefore, total no. of students=Rs (1953/2÷123/2) = 15.87
Rounding off 15.87 to 16.
There were 16 students
