23 x 72 = 1656
40 + 420 + 12 = 472
1656 - 472 = 1184 (the answer)

We can use the formula
to solve to for this

The answer is 9 because if you put those numbers in a life from smallest to biggest and take one off each side your left with 9
Answer:
1.50
Step-by-step explanation:
X = hot dog price
Y = hamburger price
5X + 4Y = 16.50
4X + 5Y = 17.25
4(5X + 4Y = 16.50)
20X + 16Y = 66
5(4X + 5y = 17.25)
20X + 25Y = 86.25
Now subtract the equations:
20X + 16Y = 66
20X + 25Y = 86.25
9Y = 20.25
Y = 2.25
Hamburger is $2.25
4X + 5(2.25) = 17.25
4X + 11.25 = 17.25
4X = 6.00
X = 1.50
Hamburgers are $2.25
Hotdogs are $1.50
