Answer:
x = 12
Step-by-step explanation:
- (10x - 20)° and (6x + 8)° are on the straight angle and they are both equal 180°
to find the value of x:
10x - 20 + 6x + 8 = 180
10x + 6x = 180 + 20 - 8
16x = 192
x = 192/16
x = 12
The answer is 36, all you had to do is multiply 9x4
Loan amount = 268 000 dollars
Interest = 6.34% annual percentage interest.
Loan will be for 30 years
=> 268 000 * .0634 = 18132.4 dollars for annual
=> 18132.4 dollars * 30 years = 543972 dollars
=> 543972 + 268 000 = 811972

Answer:
12 hours
Step-by-step explanation:
Let the number of hours be represented as h.
Sarah's surfboards charges a fee of $60 to rent a surfboard and then $10.50 per hour.
Mathematically ,
60 + 10.50h
Sally's surfboards does not charge a fee, but they cost $15.50 per hour
Mathematically,
15.50h
Equating both equations together
60 + 10.50h = 15.50 h
Collect like terms
60 = 15.50h - 10.50h
60 = 5h
h = 60/5
h = 12 hours
Therefore, the number of hours that the cost will be the same to rent a surfboard for each shop is 12 hours.
