Answer:
{3, 4, 5 }
Step-by-step explanation:
solve the inequality
3x + 1 ≤ 16 ( subtract 1 from both sides )
3x ≤ 15 ( divide both sides by 3 )
x ≤ 5
from the set {3, 4, 5, 6, 7 }
the solution set is {3, 4, 5 }
Answer:
12 km
Step-by-step explanation:
Using the formula <em>rate × time = distance:</em>
Jogging = 12 km/h × x = 12x
Walking = 8 km/h × (x + 0.5) = 8x + 4
Setting the two terms equal:
12x = 8x + 4
Subtracting 8x from both sides:
4x = 4
Dividing both sides by 4:
x = 1
Therefore, it takes 1 hour of jogging or 1.5 hours of walking to travel from the school to the pool. Thus, they are 12 km [12 km/h × 1 h <em>or</em> 8 km/h × 1.5 h] apart.
