Answer:
He have 43 bills of 10 and 13 bills of 5 
Step-by-step explanation:
5x + 10y = 495
x + y = 56 
Isolate x: 
x = 56 - y 
Substitute in the first equation: 
5(56 - y) +10y = 495 
280 -5y +10 y = 495
5y = 495 -280
5y = 215 
y = 215/5
y= 43 
Now substitute the value of y to find x: 
x = 56 - y 
x = 56 - 43 
x = 13

Answer:
   (c) 108 yd
Step-by-step explanation:
For hypotenuse c and legs a and b, the Pythagorean theorem tells you the relation is ...
   c² = a² +b²
Solving for c, we have ...
   c = √(a² +b²)
   c = √(40² +100²) = √(1600 +10000) = √11600
   c ≈ 107.70 . . . . yards
The length of the hypotenuse is about 108 yards.
