The answer of the question is A.0
The other person did not explain so I will:
(68+79+74)= 221/3 =73.7
80 x 4 = 320
320-221 = 99
He must get 99 on his 4th test.
Thanks
It would only be 10/3
Unless you are needing the mixed fraction: 3 and 1/3
Answer:
103
Step-by-step explanation:
Interior angles of a pentagon add up to 540
117+100+105+115+x=540
437+x=540
Subtract 437 from both sides
x=103
