(i need solving this using 3x3x3 elimination)

at the track meet concession stand, dylan spent $8 on two candy bars, a bottle of soda, and a
hot dog. his friend hunter spent $13 on three candy bars, a bottle of soda, and two hot dogs.
caleb purchased two candy bars, two bottles of soda, and two hot dogs for $14. calculate the
price of each item.

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

answer: idk

step-by-step explanation:

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
