C) More girls than boys prefer hamburgers over hotdogs.
A^2+b^2= c^2
48^2+b^2= 80^2
2304+b^2= 6400
Subtract 2304 from both sides.
b^2= 4096
Find the square root.
b= 64
I hope this helps!

Answer:
y = 9 - 3x
Step-by-step explanation:
9x + 3y - 27 = 0 ( add 27 to both sides )
9x + 3y = 27 ( subtract 9x from both sides )
3y = 27 - 9x ( divide through by 3 )
y = 9 - 3x
