Answer:
a < 3
n < 3
Step-by-step explanation:
We will solve each inequality one by one.
Solve first inequality :
3a - 4 < 5
add 4 both the side
3a < 9
divide 3 both the side
a < 3
Solve second inequality:

subtract 5 both the side

now multiply by -3 both the side and reverse the inequality sign
n < (-3)*(-1)
n < 3
That's the final answer. I hope it will help you.
Answer:
190 feet below sea level
Step-by-step explanation:
d = -310 + 15m
d = -310 + 15(8)
d = -310 + 120
d = -190
This situation is represented in annex.
From Pythagorean theorem you've got equation:

There isn't any solutions where x>0, so this situation is IMPOSSIBLE.
