Answer:
31.25 seconds
Step-by-step explanation:
Examine division
11.6 + 24.4 = 36 m < 50m
and 36 + 37.2 - 73.2m > 50m
50 - 36 = 14m
14 * 23.25/37.2 = 8.75 seconds
7.25 + 15.25 + 8.75 = 31.25 seconds
so it would take him 31.25 seconds to swim 50 meters.
B. 5, 9
x = 5
y = 9
y - x = 4
(9) - (5) = 4
True
hope this helps
Maybe from the equation of a line from y=mx+c
Where c ( intercept) is -12
