Answer:
X = - 4
Step-by-step explanation:
Given in problem
- x -4x - 7 = 5 -2x
Or, -5x - 7 = 5- 2x
Or, -5x + 2x = 5 + 7
Or, -3x = 12
Or, x = - 
∴ X = - 4 Answer
P ( A ) = 0.45 - probability that the land has oil,
P ( B ) = 0.8 - probability that the test predicts it
P ( A ∩ B ) = P ( A ) · P ( B ) = 0.45 · 0.8 = 0.36
Answer: The probability that the land has oil and the test predicts it is 36 %.

Step-by-step explanation:
to find the area we do the length x height of the shape
Answer:
Price > 100$
Price > 150$
Step-by-step explanation:
Let us assume that x% off of price y$ is better than x$ off.
Hence,
Hence, y > 100
Therefore, when the price is more than 100$, then only x% off on the price is better than x$. (Answer)
Again, assume that 20% off on price y$ is better than 30$ off.
Hence,
⇒ y > 150$
Therefore, when the price is more than 150$, then only 20% of on the price is better than 30$ off. (Answer)
