102 of runner's races were 10-kilometer races.
Step-by-step explanation:
Given,
Total kilometers finished = 1500 km
Number of 15 km races = 32
Number of 10 km races = x
Therefore;
15*32+10x=1500
Dividing both sides by 10
102 of runner's races were 10-kilometer races.

Answer:
Option (1).
Step-by-step explanation:
Given question is incomplete: find the complete question in the attachment.
From the given figure, coordinates of the points A and B are (0, 2) and (2, 0) respectively.
Slope of line AB =
When these points are dilated by a scale factor = 2, about the origin
Rule for the dilation → (x, y) → (kx, ky)
Where k = scale factor
Coordinates of the points A' and B' will be (0, 4) and (4, 0)
Slope of the line A'B' =
Since , both the lines AB and A'B' will be parallel.
Therefore, option (1) will be the answer.
