Answer:
x = 10
Step-by-step explanation:
3x + 55 = 9x - 5 (add 5 to both sides)
3x + 55 + 5 = 9x - 5 + 5
3x + 60 = 9x (subtract 3x from both sides)
60 = 9x - 3x
60 = 6x (rearrange)
6x = 60 (divide both sides by 6)
x = 60/6
x = 10
Answer:
x=7
Step-by-step explanation:
You simplify both sides of the equation, then isolate the variable.
Answer:
by hand because hand solution can be done by mind and can be written in copy but in calculator to solve one problem the first should delete but in copy we can write and remember.
She paid the loan at a 15% rate of interest.
Given that Lindsay borrowed $ 120,000 in a bank for a year, if she paid $ 139,290.54 on the maturity date, to determine at what rate of interest, compounded monthly, did she pay, the following calculation must be performed:
- 120,000 x (1 + X / 12) ^ 12 = 139,290.54
- (1 + X / 12) ^ 12 = 139,290.54 / 120,000
- 1 + X / 12 = 12√1.1607545
- X / 12 = 1,012 - 1
- X = 15
Therefore, she paid the loan at a 15% rate of interest.
