If he saves $6 from every $15 he gets, then getting $75 means he saves $30.
Lets says he is paid 15 dollars every hour, and from those he saved 6 dollars. If he earned 72 dollars, that means he is paid 5 times (because 75/15 is 5). So if every time he is paid he saves $6, being paid 5 times means he saves $30 ($6 *5).
Let x be equal to Jim's travel time
Let x + 2 be equal to Joan's travel time
distance = speed*travel time
6(x + 2) + 8x = 33
6x + 12 + 8x = 33
14x = 21
x = 21/14 = 3.5
3.5 hrs is the hours that Jim have been running until he met Joan.
Y=48x+44 because the rate is 44 per month which equals b plus the total 48
Answer:

Step-by-step explanation:
A
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here diameter = 12 , then radius = 12 ÷ 2 = 6 , then
A = π × 6² = 3.14 × 36 = 113.04 m²
B
The circumference (C) of a circle is calculated as
C = 2πr ( r is the radius )
Here C = 28.26 , then
2πr = 28.26 ( divide both sides by 2π )
r = 
= 
= 4.5 in
