The simpliest way to do this is to turn both fractions into decimals
7/10 goes to 0.7 and 2/5 goes to 0.4
then the equation would be 0.7x + 20 = 0.4
hope I've helped!
Given :
An equation, 2cos ß sin ß = cos ß .
To Find :
The value for above equation in (0, 2π ] .
Solution :
Now, 2cos ß sin ß = cos ß
2 sin ß = 1
sin ß = 1/2
We know, sin ß = sin (π/6) or sin ß = sin (5π/6) in ( 0, 2π ] .
Therefore,
![\beta = \dfrac{\pi}{6}\ or\ \beta = \dfrac{5\pi}{6}](https://tex.z-dn.net/?f=%5Cbeta%20%3D%20%5Cdfrac%7B%5Cpi%7D%7B6%7D%5C%20or%5C%20%5Cbeta%20%3D%20%5Cdfrac%7B5%5Cpi%7D%7B6%7D)
Hence, this is the required solution.
Answer:
The loan will be paid after 39 monthly installments.
Step-by-step explanation:
Since I am paying off a student loan in monthly installments, and after the 4th payment the remaining balance is $ 13,900, while after the 5th payment my remaining balance is $ 13,500, to determine the amount of payments in which the loan was agreed I must perform the following calculation:
13900 - 13500 = 400
400 x 5 = 2000
2000 + 13500 = 15500
15500/400 = 38.75
Thus, the loan will be paid after 39 monthly installments.
