Answer:
-38 - 12x < 200
Step-by-step explanation:
Given,
The original elevation = -38 feet,
Also, the explorer starts moving at a rate of negative 12 feet per minute.
So, the distance covered by explorer after x minutes = -12x feet,
Thus, the final elevation = original elevation + distance covered by explorer
= -38 - 12x
According to the question,
final elevation < -200 feet
⇒ -38 - 12x < 200
Which is the required inequality.
Answer:
-26/5 or -5.2
Step-by-step explanation:
First, you need to expand the parentheses:
50x+500=240
Now, subtract 500 from both sides:
50x=-260
Now, divide both sides by 50
x=-26/5=-5.2
Hope this helps!
