Answer:
She used 6.825 pints of withe paint to paint her bedroom walls
Step-by-step explanation:
We know Cathy used 9.1 pints of paint and 1/4 is blue.
first we have to calculate the white paint, we are going to calculate it by subtracting 1/4 of the total paint
1 - 1/4 = 4/4 - 1/4 = 3/4
Now that we know that 3/4 of the total paint is white, we have to multiply it by the amount of paint so we get how many pints of paint are white
3/4 * 9.1 = 6.825
She used 6.825 pints of withe paint to paint her bedroom walls
-12 = f/0.2
First, we can start out by making our goal to get the variable (f) on one side of the problem by itself. To do this, multiply both sides by 0.2.

Second, our next step is to multiply -12 times 0.2. This can be solved in your head, on a piece of paper, on a calculator, etc. (-12 times 0.2 = 2.4).

Third, our last step will be to switch sides. Basically flip the problem.

Answer:
I can't see. This is kinda blurry
Answer:
A general exponential equation is written as:
y = a*(b)^x
Where:
y represents the amount of something as a function of the variable x, where x is an independent variable.
a is the initial amount, this is, the value of y when x = 0.
b is the rate of growth, this defines how much changes the value of y as x increases.
