Terri can swim 3 laps in 2.5 minutes. To find how long it takes to swim 20 laps, you can make a proportion.
Put the amount of laps on the top and the time(minutes) at the bottom.
Cross multiply:
Divide by 3:
It would take Terri OR minutes to run 20 laps.

1 B 28 is not divisible by 3
2. C 12 is divisible by 12
3. 5 is the greatest common factor
4. 23 is prime
5. 47 is prime
6 4 is the greatest common factor
Reflection. A reflection is what appears to be the same distance from the other side of the mirror.
Combine like terms so 12b=12b
Then divide by 12 which then b=1
