-3.5x + 9.1x + 1.7 - 0.3 = 5.6x + 1.4
Answer:

Step-by-step explanation:
The circumference of a circle can be found using the following formula:

where d is the diameter. We are given the radius, so let's find the diameter.
The diameter is twice the radius.

The radius is 15 feet.

Multiply.

Now we know the diameter. Substitute 30 feet in for d.


We are using 3.14 for pi, so substitute it in.

Multiply.

The circumference of the circle is 94.2 feet.
Create an expression. Solve for x
22+66x=66+33x
Subtract 33x from both sides
22+33x=66
Subtract 22 from both sides
33x=44
Divide both sides by 33
x=44/33=4/3 or 1.3 hours

2 ways to do this...
(1) 3.59 * 1.06 = 3.8054 rounds to 3.81
(2) 3.59 + 0.06(3.59) = 3.59 + 0.2154 = 3.8054 rounds to 3.81
