You have to substitute. So like number 1 is 3+5 because the value of t is three. 2. is -2.
3. is -9.
4 is 0.
5 is -12.
6 is 24.
7 is -96.
8 is 64.
9 is 7.
10 is 2.
Let 't' represent the time of the walk in minutes.
5.1*t = 220
t = 43.14 min
The person needs to walk at least 43.14 minutes to but at least 220 calories.
Answer:
x = 83/3.

83 = 3x
x = 83/3.
