9 * 5 = 45
5 * 9 = 45
15 * 3 = 45
3 * 15 = 45

When you set up equations like this, look at the units for help. They cancel out during division and multiplication like numbers to give desired quantities. Rates can be reversed if need be (3 meters/sec or 1/3 sec/meter).
time × (distance / time) = distance
See.. time/time = 1; leaving distance
Subtract the rate of the opposing walkway...
t × (3 m/s - 1 m/s) = d
2t = d
Answer is then A.
29: It is D because it is in order, from least to greatest
30: It is J because the scale from 1-2 is 8, and it is on the second mark so it is
1 1/4
The answer is 1080 hope this helped may i have brainliest
