Answer:
C.
Step-by-step explanation:
Pretend pi, b, and c are just regular numbers, and a is the variable. How would you get a alone on one side? First write the equation.
c = 8πab
c = 8 x π x a x b
Use the commutative property:
c = 8 x π x b x a
Use the associative property:
c = (8πb)a
Divide both sides by (8πb) to get a alone on one side.
I really hope this helps you =)

Answer:
c = 15d + 30
Step-by-step explanation:
Hey there!
This can be represented by an equation of a line, where the number of days is our x-values(d), and the price is our y-values(c).
The price for one day ($45) and the price for 4 days($90) are specific points on that line.
The points are (1, 45) and (4, 90).
We can first find the slope of the line:
- As the price rises 45, the days increase by 3
- Slope = rise/run
- Slope = 45/3
- Slope = 15
Now we can find the base price, by plugging the slope and a point into the equation y = mx + b.
Solve for b:
- y = mx + b
- 45 = 15(1) + b
- 45 = 15 + b
- 30 = b
The base price (b) is 30.
The equation is
