Use identify , so
Sorry if this is confusing.
these are the answers is order:
10, 22, 57, 36, 42, 60, and 16,000.
Hope these helped! :D
Add all the times together:
10 + 25 + 15 = 50 minutes total.
For the ratio divide the time for weights by total time:
25/50 which reduces to 1/2
The ratio is 1/2
Actually I didn't see the (-5, -27), the answer would be -2.
