I basically converted them all into decimals and rounded
Team 1- 0.75
Team 2- 0.8
Team 3- 0.775
Team 4- 0.825
Team 5- 0.725
Team 6- 0.7625
Team 7- 0.7875
Team 8- 0.8125
Team 4 collected the most
Team 5 collected the least
Simplified: 3x+7y+(-2y)+9
Coefficient of y: 5
Constant: 3 and 6
The sum of all angles in a triangle is equal to 180.
75 + 70 + 5 + 3x = 180
150 + 3x = 180
3x = 180 - 150
3x = 30
x = 10
Third angle:
5 + 3(10)
35
Answer:
(8 / x) + (21 / y)
Step-by-step explanation:
Given that:
Average driving speed = x mph
Miles driven to work = 8 mile
Miles by train to work = 21 miles
Average train speed = y
Total time taken to get to work. :
Recall : time taken = distance / speed
Hence,
Time taken =) total distance / average driving speed)
Total time taken = (8 / x) + (21 / y) hours
Total time taken = (8 / x) + (21 / y) hours
