It would take the bud 15 minutes to travel at 125
4 and 8 are corresponding angles. Corresponding angles are on the same side of parallel lines cut by a transversal
Equation: 120 ≥ 10n + 20
Subtract 20 from both sides,
100 ≥ 10n
Divide both sides by 10,
10 ≥ n
It means, it is equal or Smaller than 10.
So, the answers would be: 7, 8, 9, 10
Hope this helps!
