Step-by-step explanation:
Pear cost=x
Orange cost=x-y
4 pears= 4x
6 oranges=6x-6y or x-y x6
Use ratio.
Pears: x cents
4 Pears: 6x cents
You x4 on each side. Same with oranges.
Orange: x-y
6 oranges: x-y x6
You x6 on each side.
Answer:
x=9
Step-by-step explanation:
2x+12=5x-15
3x=27
x=9
There are 6 balls to every box (a ratio of 6 to 1). Therefore, when there are 78 balls, there are 13 boxes.
3t = 5(3-t)
3t = 15 - 5t
3t + 5t = 15
8t = 15
t = 15/8
t = 1 7/8
7/8 * 60 mins = 52.50 minutes
t = 1 hour and 52.5 minutes
It took Stu 1 hour and 52.5 minutes to hike the trail one way.
