Answer: x= 5-y/2
y= 5-2x
Step-by-step explanation:
2x + y= 5
4x + 2y=10
Addition of the two equations gives:
6x + 3y = 15
6x= 15- 3y
x= 15-3y/6 or simplified to x = 5-y/2
3y= 15- 6x
y= 15-6×/3 or simplified to y= 5-2x
Answer: 50.25mi/h
Step-by-step explanation:
1. You must calculate the average speed in the first part of the trip with the following formula:
Where is the distance in the first part of the trip and is the time in the first part of the trip.
Then:
2. Now, calculate the average speed in the second part of the trip:
3. The average speed of the bus for the entire trip:
Let us assume the number of free throws attempted this season = x
Number of free throws made = 93
Percentage of free throws made = 75%
Then
(75/100) * x = 93
3x/4 = 93
3x = 93 * 4
x = (93 * 4)/3
= 31 * 4
= 124
So the total number of free throws attempted is 124. I hope the procedure is clear enough for you to understand. You can always attempt similar type of problems on your own using the method described.
