Answer:
The 3rd statement best describes the graphs.
Step-by-step explanation:
The 3rd statement best describes the graphs because they must be similar. The two triangles cannot be congruent because Triangle A must be dilated to become Triangle B.
Multiplying by a scale factor of 1/2 would cause the shape to shrink, but multiplying by a scale factor of 2 would cause the shape to grow.
Answer:
Multiply (x)
Step-by-step explanation:
If you multiply 15.5 x 3.90 it will give you the total amount of money Chris and Jeff earned.
3 2/3=11/3
14 2/5=72/5
11/3x72/5=264/5
264/5=52 4/5
Let the medium angle be B degrees
the small angle be A degrees
the large angle be C degrees
Then
C = 2 B + 20 ..................X
5 B = A + C ..................Y
Sum of all angles
A + B + C = 180 .............Z
Applying Y in Z
5 B + B = 180
6 B = 180
B = 30
From X C = 2 x 30 + 20 = 60 + 20 = 80
From Y 5 x 30 = A + 80
150 = A + 80
150 - 80 = A = 70
Hence medium angle B = 30 degrees
the small angle A = 70 degrees
the large angle C = 80 degrees
The answer is 10x+8y-12 if the problem was -6x - 12 + 8y + 16x because you added an extra negative at the start.
