The expression Carey is solving is:
Simplify the expression as follows:
So, in Carey's calculation the third step is incorrect.
Instead of 27 the three-fourth must be multiplied by 36 to get the correct answer.
Thus, the correct option is (A).
Answer:
Option (C)
Step-by-step explanation:
In this question we will use the property " similarity of the triangles".
If DE and AC are parallel two triangles BED and BCA will be similar, corresponding sides of the triangles will be proportional.
Option (A).
But
Therefore, given triangles are not similar.
AC and DE are not parallel.
Option (B).
But
Therefore, AC and DE are not parallel.
Option (C).
2.5 = 2.5
Therefore, AC║DE.
Option (D).
But
Therefore, AC and DE are not parallel.
Option (C) will be the answer.
Answer:
3A : 3(a)+8(b)+2(c)
3B: 3(20)+8(8.50)+2(40)=208
3C: 208-15%=208*0.15=31.2
208-31.2=176.8
3D: 176.8+6%=176.8*1.06
187.41
