<span>"Simplifying
0.2y = 0.5x + 0.1
 Reorder the terms:
0.2y = 0.1 + 0.5x
Solving
0.2y = 0.1 + 0.5x
Solving for variable 'y'.
 Move all terms containing y to the left, all other terms to the right.
 
Divide each side by '0.2'.
y = 0.5 + 2.5x
Simplifying
y = 0.5 + 2.5x"</span>
        
             
        
        
        
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 %. 
        
             
        
        
        
Answer:
x = 40/3
Step-by-step explanation:
2/3 = (8/x) + 6
-6                -6
2/3 - 6 = -16/3
-16/3 = 8/x
*x          *x
(-16/3)x = 8
+16/3     +16/3
x = 40/3
