Answer:
Well, it depends on how many days he exercises. If Juan exercises for 30 minutes a day, multiple 30 by how many days he exercises.
Example:
1 Day = 30 Minutes
2 Days = 60 Minutes / 1 Hour
3 Days = 90 Minutes / 1 Hour, 30 Minutes
4 Days = 120 Minutes / 2 Hours
5 Days = 150 Minutes / 2 Hours, 30 Minutes
6 Days = 180 Minutes / 3 Hours
7 Days = 210 Minutes / 3 Hours, 30 Minutes
And so on..., hope this helps! :)
Answer:
x = -1
y = -5
Step-by-step explanation:
9(2y+9) - 8y = 31
18y + 81 - 8y = 31
10y + 81 = 31
10y = -50
y = -5
2(-5) + 9 = x
-10 + 9 = x
-1 = x
