(Z-6) divided by 3 for z= 15.9
Simply plug in \(\sf{z=15.9}\) into \(\sf{\frac{z-6}{3}}\)So:\(\sf{\frac{15.9-6}{3}}\)Simplify that more:\(\sf{\frac{9.9}{3}}\)And that finally becomes \(\sf{3.3}\)So when \(\sf{z=15.9}\) the answer will be \(\boxed{\sf{3.3}}\)
(z-6) turns to (15.9-6) which is 9.9 then divide that by 3 and you get 3.3
