9 Polyester fill and 5 down fill sleeping bags were sold.
Step-by-step explanation:
Let,
Polyester fill sleeping bags = x
Down fill sleeping bags = y
Price of 1 polyester fill bag = $79
Price of 1 down fill bag = $149
According to given statement;
x+y=14 Eqn 1
79x+149y=1456 Eqn 2
Multiplying Eqn 1 by 79
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 70
Putting y=5 in Eqn 1
9 Polyester fill and 5 down fill sleeping bags were sold.

Answer: x = 20
Step-by-step explanation:
We can use the pythagorean theorem:
x^2 + 15^2 = 25^2
x^2 + 225 = 625
We can subtract 225 from both sides:
x^2 = 400
We can take the square root of both sides:
x = 20.
