7) 93,000,000 - 63,000,000 = 30,000,000
150 - 3x = 120 + 2x | +3x
150 = 120 + 5x | -120
30 = 5x | :5
6 = x
Answer:

Step-by-step explanation:
The area of the circle is 
The area of the triangle is 
Hence, the probability of a randomly selected point within the circle falls in the red shaded area is 
Slope-intercept form is y = mx + b, so your answer would be:
y = -5x + 8
