I believe it would be .21m. So for example.The memory stick is sold normally for $14, so to plug it into the equation it would be: .21(14), which gives you the discount of $2.94. Subtract that amount from the original price, and that gives you the sale price. .21(14)=2.94 14-2.94=11.06~~~~~Sale price
Plug in -3x-(3)=18
Add three both sides
-3x=21
Divide -3 both sides
x=7
Answer: The outbound trip is 18 miles per hour
Step-by-step explanation:
Let x represent the speed of the plane.
An aircraft carrier made a trip. Let us assume that this trip was outbound. The trip there took 5 hours.
Distance = speed × time. Therefore
Distance = 5x
The trip back took 6 hours. It averaged 3 mph faster on the trip there then on the return trip. This means that the speed on the trip back is x - 3 mph.
Distance = 6(x-3) = 6x - 18
Since the distance is the same,
5x = 6x - 18
6x - 5x = 18
x = 18
The speed on return or inbound trip would be 18 - 3 = 15 mph
Answer:
1/3
Step-by-step explanation:
rate of change, or slope, is the change in y's divided by the change in x's
(5 - 3) / (7-1) = 2/6 = 1/3
