This is pretty easy
(39 + x) / 2 = 44
39 + x = 88
x = 49
32 divided by 127 and the second one, i dont know
The formula for this would be the Pythagorean Theorem. This meaning a²+b²=c²
so a²+15²=25, 15²=225, so a²+225=25, move the 225 over and a²=250, square root of 250 is 15.8 rounded up to 16 feet so, so a=16. but idk that might not be right
38.95-11.98= 26.97
Divide 26.97 by 3 which gives you 8.99 so therefore the cost of each pizza is 8.99
And the equation would be
P= 38.95-11.98/3
