At a restaurant, an order of 3 tuna sandwiches and 2 sodas costs $15.75. An order of 3 tuna sandwiches and 4 sodas costs $18.75. How much more
does 1 tuna sandwich cost than 1 soda?

step-by-step explanation:

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

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

i believe the correct answer is b.

-2/

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
