Y axis is 1.5 and x axis is 1 and make them meet in the middle and add and repeat the process
Y because if you add them you will get 10x =-10
The y will be eliminated because you have positive 3 -4
Answer:
N = 10
Step-by-step explanation:
-17+ x/5 = 33
You have to find x, in this case is N
x/5 = 33 + 17
x/5 = 50
x= 50/5
x =10
N= 10
You must calculate how many ways can 2 people be selected from 65.
The formula is:
n! / r! * (n-r)! =
65! / 2! * 63! =
65*64*63! / 2 * 63! =
65*64 / 2 =
