Answer:
what number do you want to "Multiply by 3, then subtract 4."
Example:
(12 x 3) - 4
36 - 4 = 32
Initial Deposit = $7000
It means P= $7000
rate of interest = 10%
So , r = 0.10
compounded quarterly , so n = 4
and we have to find the amount after 5 years , So t = 5
Now the formula we use here is





So amount after 5 years = $11470.315
So here's gives that
total weight of 25 bags = 50 x 25
= 1250
total cost of 25 bags weighing 50 kg is = 15000
cost of 1 kg = 15000 ÷ 1250 = 12
now total weight of 15 bags weighing 30 kg = 450
cost per kg = 12
cost of 15 bags weighing 30 each = 450 x 12
Answer = 5400 rupees.
Alright, lets get started.
The answer Sandra got is correct that is zero but there are some mistakes she made while writing steps.
Incorrect step
Because as per even/odd identity,
Cot (-Θ) = - cot (Θ)
Hence

Now,
It could be written as


0
Hence the answer is 0. : Answer
Hope it will help :)
X+(x+1)+(x+2)+(x+3)=156
4x+6=156
4x=150
x=37.5 (not an integer)
If x=37 you get 37+38+39+40=154 and if x=38 you get 38+39+40+41=158[/tex]
