Answer:
Step-by-step explanation:
<u>Put input value instead of the x into equation and calculate the output:</u>
<u>x = -4, then find the value of y:</u>
- y = -5(-4) - 7 = 20 - 7 = 13
The output is 13 when the input is -4
Subtract 24.45 from itself the subtract 13.27 by 24.45 and should t=37.73
50 yards for 1 lap
50 yards x 18 laps = 900 total yards
now divide the amount he swam by the total amount he wants to swim:
738 / 900 = 0.82 = 82%
Answer is B
