Answer:
Step-by-step explanation:
Let the speed of the car is x, then the speed of motorcycle is x + 20
The distance = 120 km
<u>Time:</u>
- 120/x = 120/(x + 20) + 1
- 120(x + 20) = 120x + x(x +20)
- 120x + 2400 = 120x + x² + 20x
- x² + 20x = 2400
- x² + 2*10x + 10² = 2500
- (x + 10)² = 50²
- x + 10 = 50
- x = 40
Speed of the car is 40 km/h
Speed of the motorcycle is 60 km/h
Hello!
Throughout this problem, we will add or subtract values from our original balance.
In your checkbook, there was 298.72 dollars, and then you deposited 425.69 dollars. The function you would do is addition.
$298.72 + 425.69 = $724.41
If you wrote a check, then the amount you wrote is removed from your checkbook.
$724.41 - $29.72 - $135.47- $208.28 = $350.94
Then, the bank deducted 5 dollars from your account.
$350.94 - $5.00 = $345.94
This leaves you with $345.94 at the end of the week.
Therefore, your answer is choice C, $345.94.
