B. Half the speed of the car. and C. The number of different colors on the page.
Variables are symbols for unknown values, so you have to find the statements that contain an unknown value.
A. 27 ⇒ The point value is known, so there is no variable.
B. 
X ⇒ Since the speed of the car is unknown, the variable X represents the speed of the car. This variable is multiplied by or divided by 2 to get half the speed of the car.
C. X ⇒ The number of different colors is not known, so the variable X represents the number of different colors.
D. 80 ⇒ There is nothing unknown in the statement.

Answer:
$33.92
Step-by-step explanation:
First, we have to find how much the sale price for the tennis racket is before tax.
100% - 20% = 80% Marcus has to pay 80% of the original price.
80% * 40 = .8 * 40 = 32
Marcus has to pay $32 for the tennis racket before tax.
6% = .06 (tax percentage)
.06 * 32 = 1.92 ————> tax
Add the tax with the sale price.
32 + 1.92 = 33.92
Marcus has to pay $33.92 for the tennis racket.

Answer:
Step-by-step explanation:
Okay, so the goal is to isolate c on one side with all the other terms on the other side. So, let's start by dividing both sides with 12h. After we do that, we will be left with 
. Now, we can subtract both sides by b, and we will be left with 
. Yay! We've now isolated c and that is our final answer!
Hope this helped! :)
