Answer:
2. chord theorem; t = 10.5
3. chord theorem; x = 5
Step-by-step explanation:
For both of these problems, the relevant theorem is the "intersecting chord theorem", also referred to as the "chord theorem." It tells you the product of the lengths of the parts of one chord is equal to the product of the lengths of the parts of the other chord.
2. 20t = 10·21
t = 210/20 . . . . divide by 20
t = 10.5 . . . . . . . simplify

3. 10(x +4) = 15(x +1)
10x +40 = 15x +15 . . . . . eliminate parentheses
25 = 5x . . . . . . . . . . . . . subtract 10x+15
5 = x . . . . . . . divide by 5
Answer:
this question is incomplete
Step-by-step explanation:
For part a, yes because each student is paying the same amount
For part c, each student is paying $15 to go
For part d, it's $1800
For part e, it would be 95 students
1 kilometer = 1000 meters
3 kilometers would be 3000 meters
Divide total meters by number of parcels:
3000 / 10 = 300
The answer is 300 meters
