Answer:
1) Solutions are x = 3 and x = 5/3
2) Solution are x ≤ 13/2 and x ≤ -3/2
Step-by-step explanation:
1) Given absolute inequality,
|3x-7| = 2
⇒ 3x - 7 = ± 2
⇒ 3x = 7 ± 2



2) l 2x-5 l ≤ 8
⇒ 2x-5 ≤ ±8
⇒ 2x ≤ 5 ± 8



The correct answer is $44.20.
If we add up all the tips, the total is $442. If we divide this by the number of days (10), then we find the mean.
442 / 10 = 44.2
Answer:
Approximately 23.6
Step-by-step explanation:
So first find the fraction of the whole circumference the arc is.
270 ÷ 360 = 0.75
The circumference is 10π
0.75 * 10π = 7.5π
7.5π = 23.5619449019 ≈ 23.6
