At a store, a hat has a regular price of x dollars.
During a sale, the price of the hat is discounted
by 20%. The expression 0.8x describes the
discounted price, in dollars, of the hat. Which
expression also describes the discounted price, in
dollars, of the hat?
A.
0.2x
c.
x-0.2
B.
X-20
D.
/- 0.2x

the answer is 2/54

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
