Answer:
-12
Step-by-step explanation:
2(6a-2b)-8(-2)
=2[6(-1)-2(4)]+16
=2[-6-8]+16
=2[-14]+16
=-28+16
=-12
Given:
Principal = Rs. 2000
Rate of interest = 20% p.a. compounded quarterly.
Time = 1 year
To find:
The compound interest.
Solution:
Formula for amount:

where,
P = Principal
r = Rate of interest
t= Time
n = number of times interest compounded in an year.
Putting P=2000, r=0.2, n=4 and t=1, we get




Now, the compound interest is



Therefore, the compound interest is Rs 431.0125.
Answer:
I believe the balance would be $1,545.00
It is proportional because all the sides are equal.
Answer:
n = 2
Step-by-step explanation:
1/2(n-4) - 3=3- (2n+3)
Expand the brackets.
1/2n-2-3=3-2n-3
Add or subtract the like terms.
1/2n-5=-2n
Add 2n and 5 on both sides.
1/2n+2n=5
Add like terms.
5/2n = 5
Multiply both sides by 2/5.
n = 5 × 2/5
n = 10/5
n = 2
