Answer:
x = -4
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS =
Parenthesis
Exponents (& Roots)
Multiplication

First, divide 3 from both sides of the equation:
(3(-3 - 3x))/3 = (27)/3
-3x - 3 = 27/3
-3x - 3 = 9
Next, isolate the variable, x. Note that what you do to one side of the equation, you do to the other. Do the opposite of PEMDAS.
First, add 3 to both sides:
-3x - 3 (+3) = 9 (+3)
-3x = 9 + 3
-3x = 12
Next, divide -3 from both sides:
(-3x)/-3 = (12)/-3
x = 12/-3
x = -4
x = -4 is your answer.

Answer:
6 1/9 hours
Step-by-step explanation:
10 3/9 - 4 2/9 = 6 1/9
The volume of a sphere uses the following formula:

Because the question asks to use 3.14 in place of pi, the formula will now look like this:

We are given a diameter of 118 feet. The radius is half of the diameter, so divide the diameter by 2 to find the radius:


Plug this value into the formula, and solve with a calculator:

Although our result is one cubic foot off, the answer is

A. 859,852ft^3.
(859,852 is the result if the constant in the given formula is 4.18666, but the result with infinitely repeating numbers is 859,853.)</span>
