1.29=a/3.5(1-a)
a=0.82
How do I solve for a? What does the equation look like?
1.29=a%2F%283.5%281-a%29%29
1.29=a%2F%283.5-3.5a%29
1.29%283.5-3.5a%29=a%283.5-3.5a%29%2F%283.5-3.5a%29
1.29%283.5-3.5a%29=a%2Across%28%283.5-3.5a%29%29%2Fcross%28%283.5-3.5a%29%29
1.29%283.5-3.5a%29=a
4.515-4.515a=a
4.515-4.515a%2B4.515a=a%2B4.515a
4.515=5.515a
4.515%2F5.515=5.515a%2F5.515
.8186763373=a Which rounds off to:
highlight%28a=.82%29
Happy Calculating!!!
