Answer:
A. 10
Step-by-step explanation:
First put the numbers in order from least to greatest then find the two numbers in the center of that since there is an even number of numbers there will be two the add and divide by two and you get 10.
1,2,7,9,11,15,19,20
9+11=20
20/2=10
long way
12 x 11 x 10 x 9 x 8 x 7 x6 x5 x4 x3x2/ 10x9x8x7x6x5x4x3x2x
but you can shorten that by crossing out identical numbers so you get 12 x 11
12 x 11 = 132 combinations
(-1,x) you didnt say how many units up
3(10) + 5y = 20
5y = 20 - 30
5y = - 10
y = - 2
