Answer:
a = (p - b)/2
Step-by-step explanation:
Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and =

First, subtract b from both sides:
p (-b) = 2a + b (-b)
p - b = 2a
2a = p - b
Next, divide 2 from both sides:
(2a)/2 = (p - b)/2
a = (p - b)/2
a = (p - b)/2 is your answer.

It is given to us that the interest rate is 2%.
We know that 2% can be rewritten as . Now, we also know that in decimal form, .
Therefore, the interest earned on d dollars at an interest rate of 2% will be "2% of d" which can be rewritten as. This is because in math, "of" means the same as multiplication.
Thus, out of the given options, the last option is the correct option.
Answer:
Cookie=0.5, Apple=1.5, sandwich= 3
Step-by-step explanation:
Lets say cookie = x, then sandwich = 6x since sandwich is 6 times more expensive, apple = 3x. function: 6x+3x+x =5
10x=5
x=0.5
You are correct. The answer is 40 degrees. Its supplementary angle is 40 degrees since it adds up 180, and angle 1 is equal to that angle.
