Step-by-step explanation:
The answer isnt on there? unless it's A
Rise Over Run
From Yint you go up two and left two making your answer 2 over -2 but that would just be -1 making your answer y=-x
Cost of basic car = $8250
Optional cost = $324
Total cost of basic car and optional items for John= (8250 + 324) dollars
= 8574 dollars
Then
Percentage of sales tax = 6%
Amount of sales tax = 8574 * (6/100) dollars
= 514.44 dollars
License and registration fee combined = $50
Then total cost of John in regards to buying the car = 8574 + 514.44 + 50
= 9138.44 dollars
So option "C" is the correct option in regards to the question given.
Let's make these two fractions have a common denominator and an improper fraction:
1 1/8 = 9/8 = 63/56
2 3/7 = 17/7 = 136/56
63/56 + 136/56 = 199/56 = 3 31/56
So in total, he practiced 3 31/56 hours this week.
He practiced 1 17/56 hours longer on Tuesday than Monday.
