Can somebody please answer these two math problems!

1. A football team gained 4 yards in one play. In the next play, the team lost 4 yards. What is
the team's net yard gain?

2. Between 8 a. m. and 3 p. m. on a summer day, the outdoor temperature increased by 23º.
Between 3 p. m. and 10 p. m., the temperature decreased by 23°. What was the net change in
temperature from 8 a. m. to 10 p. m.?

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

you must wait until 2 people answer to award brainliest. i'm pretty sure that it should be next to the "" and "comments" buttons.  

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.
