Answer:
B
Step-by-step explanation:
(7^x)^4 is equal to 7^(4x).
7^2 * 7^3 is equal to 7^(2+3) which is equal to 7^5.
7^5 / 7^(3x) is equal to 7^(5 - 3x).
you wind up with 7^(4x) is equal to 7^(5 - 3x)
this is true if and only if 4x = 5 - 3x.
Answer:
The time period was of 5 years.
Step-by-step explanation:
The formula to compute the simple interest is:

The information provided is as follows:

The time period is same for both the amounts.
Compute the time t as follows:







Thus, the time period was of 5 years.
If first angle = x then second angle = 2x and third angle = 2x*3 = 6x
so 6x + 2x + x = 180
9x = 180
x = 20
third angle = 6 *20 = 120
