69.75 x 0.05 = $3.49 discount
$69.75 - $3.49 = $66.26 discounted price with tax
66.26 x 0.18 = $11.93 tip
Discounted price with tax + tip

Answer:
v = 72 km/h
Step-by-step explanation:
Given that,
The distance covered by the Patrick, d = 288 km
Time taken, t = 4 hours
We need to find the average speed of Patrick. We know that the average speed of an object is equal to the total distance covered divided by total time taken. Let it is v. So,

So, his average speed is equal to 72 km/h.
J because this is a quadratic function which is shaped like a u upward
X would equal 9. Subtract 18 from both sides then divide by two to get 9 as X
