Six college buddies bought each other christmas gifts. they spent $261.12 $120.52 $186.23, $298.97 $171.55 $263.93

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

27 +27 or 27times 2=54

the diffrence is 0
