Answer:
x = 19°
Step-by-step explanation:
Given that < (6x + 1)° + < (3x + 8)° are supplementary angles whose sum = 180°
6x + 1 + 3x + 8 = 180°
Add common terms:
9x + 9 = 180°
Subtract 9 from both sides:
9x + 9 - 9 = 180° - 9
9x = 171°
Divide both sides by 9 to solve for x:
x = 19°

Step-by-step explanation: it took that already
Since it is 100 minutes of stretching and scrimmaging, we can subtract the 10 minutes we know is stretching. 90 minutes is equal to 2/3 of the practice then. Divide by 2 and multiply by 3 to get the entire time of the practice or 135 minutes. However, you asked for it in hours, so we can subtract 120 minutes because this is 2 hours. 15 minutes is 1/4 of an hour. So practice took 2&1/4 hours. Hope that helps.
