3x+y-z=4 -3x+2y+2z=6 x-y+2z=8

homozygous. one is homozygous, while two is heterozygous.

if i put something wrong your not gonna like it so rather not say nothing.

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
