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

Answer:
D
Step-by-step explanation:
If the scale is 1 centimeter per 8 miles, and there is a distance of 51.5 centimeters on the map, what you have to do is multiply 51.5 and 8
51.5 times 8 is 412.
The actual distance is <u>412 miles</u>
Percent decrease=(decrease)/(original) converted to percent
change=120 to 52
120-52=68
change or decrease=68
original=120
68/120=0.5666666=56.6666%
about 57%
