7/8-5/8= 2/8 and if you reduce 2/8 by 2 it becomes 1/4. So 1/4 is your answer. Hope This Helps :D
Answer:
corresponding angles- 4 and 8, 3 and 7, 1 and 5, 2 and 6
same side interior angles- 2 and 5, 3 and 8
alternate interior angles- 3 and 5, 2 and 8
alternate exterior angles- 1 and 7, 4 and 6
Step-by-step explanation:
Answer:
14
Step-by-step explanation:
1/2x = 1/7x + 5
1/2x - 1/7x = 5
7/14x - 2/14x = 5
5/14x = 5
x = 5 * 14/5
x = 14
You calculate the number of ways that 2 people can be chosen from 10.
The formula:
n! / r! * (n-r)! =
10! / 2! * 8! =
10 * 9 * 8! / 2 * 8! =
10 * 9 / 2 =
45 handshakes
