Answer:
B) 666.6 miles per hour
Step-by-step explanation:
To solve this question, divide the 4000 miles with the 6 hours to get an answer in units of X miles per hour.
4000 miles/6 hours = 666.6 miles per hour
Let's simplify them top to bottom.
6(x + 2) < x - 3
6x + 12 < x - 3
5x + 12 < -3
5x < -15
x < -3
This one checks out.
3 + 4x <= 2(1 + 2x)
4x + 3 <= 4x + 2
This is a problem. In no world is 4x + 3 ever less than or equal to 4x + 2. This one has no solution.
Answer: (-0.0549,-1.0732)
Answer:
x = 4
Step-by-step explanation:
180 = 102 + 24x - 18
- 102 - 18 = 84
- subtract 84 from both sides
- 96 = 24x
- divide both sides by 4
- 4 = x
