Y=4.1 because it if take ten. And multiply it by three then take negative 9Y equals seven and divided by nine gives you 4.1
All the steps were correct except the final statement. The
mistake was in Line 6.
Line 6 triangle ABC is congruent to triangle EFD by
SAS.
<span>This does not follow. The SAS postulate states
that if two sides and the included angle of one triangle is congruent to two sides
and the included angle of another triangle. The student only proved that one side
of the triangle (AC) is congruent to the side of another triangle (EF) .</span>
Answer: -0.71
Step-by-step explanation:
<span>Analogicaly as in the previous question - firstly let's find the common denominator for those fractions:
2/3 = 12/18
2/9 = 4/18
5/6 = 15/18
11/18 = 11/18 :)
From the least to the greatest:
2/9, 11/18, 2/3, 5/6</span>
