Price of one pretzel = $1.5

Step-by-step explanation:

Let the price of a hot dog =

Let the price of a drink =

Let the price of a pretzel =

As per the given question statement:

To find:

The price of one pretzel, i.e.

Multiplying (3) with 2 and subtracting (1) from it:

..... (4)

Multiplying (3) with 4 and subtracting (2) from it:

..... (5)

Multiplying (4) with 4 and subtracting (5) from it:

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

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.
