I will use 'hr' to mean hour and 'hrs' to mean hours.
<u>The airplane flies:</u>
200 miles per hr
400 miles per hr
600 miles per hr
Average speed = Total distance ÷ total time
= (200 + 400 + 600)miles ÷ 3hrs = 400miles/hr
Time = Distance ÷ Average speed
= 2000miles ÷ 400miles/hr = 5hrs
3x - 1 = 9x + 2
3x (-3x) - 1 (-2) = 9x (-3x) + 2 (-2)
-3 = 6x
-3/6 = 6x/6
-1/2 = x
hope thsi helps
Answer:
Up to 10
Step-by-step explanation:
- Cost of fish = $3.99
- Limit of money = $40
- Number of fish = x
<u>Inequality:</u>
- 3.99x ≤ 40
- x ≤ 40/3.99
- x ≤ 10.02
Below sea level would mean in the negatives
So I would say -3
(-3, 6) includes all numbers between -3 and 6 but it does not include -3 and 6.
when you put square parentheses you include the number on the edge
so if an anwser includes all numbers between -3 and 6 and the number 6 it's correct to write (-3,6]
