Answer:
the area of the circle: 25π
Step-by-step explanation:
45/4 π = 11.25π
9/10π = 0.9π
11.25π / 0.9π = x / 2π .... 360° = 2π
x = (11.25π x 2π) / 0.9π = 25π
Add the amount of choices, and divide by the number of customers surveyed.
40 + 32 + 8 + 20 = 100
40 customers were surveyed
100/40 = 2.5
The average number should be D) 2.5

Answer:
x=x
Step-by-step explanation:
3x - 2 = 3 (x - 2/3)
3x - 2 = 3x - 6/3
3x - 2 = 3x - 2
- 2 - 2
3x = 3x
/3 /3
x = x
