That is a ratio. 7 x 3 = 21 and 13 x 3 = 39.

Answer:
Explain how subtracting 4/5 - 3/5 involves subtracting 4 and 3
Step-by-step explanation:
Trains A and B, 200 km apart on the same straight track, travel at speeds of 50 km/hr and 65 km/hr respectively. At the end of 1 hour, the distance between the trains could not be
A. 85 km
B. 115 km
C. 185 km
D. 215 km
Apparently, the answer is B.) 115 km, but I need a solution.
When the dilation is centered on the origin, you can multiply each of the individual coordinates by the scale factor.
All the coordinates are ±5 and the scale factor is 1/5. Multiplying those gives ±1. The only selection with all coordinates being ±1 is
.. Selection A.
You can check to see if the signs agree in detail. (They do.)
The whole number factors are 1, 2, 4, 5, 10, 20
