You need to make sure all of the equations are proportional and if not than it isn’t.
I say less but if I’m wrong sorry
<span>11-4(0.2)+2
1</span>1-0.8+2
12.2
step 1 LCD of 5 and 3 is 15
step2 convert the fractions to 15th's
-3/5 * 3/3 = -9/15
2/3 * 5/5 = 10/15
step3 -9/15 + 10/15 = (-9 + 10)/15
= 1/ 15 (answer)
Answer:
A: Yes: triangle DBC is a dilated figure of DEF so their sides would be congruent is scaled to equality. Similar implies that the two triangles could be equal if you use transformations (translation, reflection, etc) and a dilation is a form of translation
B: BC; each of the sides are scaled and looking at the two triangles it is a) easy to physically determine that they are the same and b) their placements within the triangle indicate their alignment
C: C; Once again physicality and placement indicate the alignment of the two and both of them are 90 degrees
