7h + 6b = 35.50
5h + 6b = 30.50

The difference between the 2 totals spent is $5, and there were the same number of burgers, but 2 fewer hotdogs. So $5/2 = $2.50, the cost of a hot dog. Substitute that into the equations to solve for burgers (b)

5(2.50) + 6b = 30.50
12.50 + 6b = 30.50
6b = 18
b = 3

Check the work:
7(2.50) + 6(3) =
17.50 + 18 = 35.50

(Quick please ) !!!!!!!!!!!!!!!! Help me!!!!! find the surface area of the rectangular prism!!!!!! thank you
Aleks [24]
You can do this !

The rectangular prism has

                   -- length = 10 cm
                   -- width  =  7 cm
                   -- height =  3 cm.

-- The area of the top and bottom is  (length x width)  each.

-- The area of the left and right sides is  (length x height)  each.

-- The area of the front and back is  (width x height)  each.

There.  I just laid out all the schmartz you need to answer this question.
The rest is all simple arithmetic, and you're perfectly capable of turning
the crank and getting the answer.  You don't need anybody else to do
that part for you.

Don't forget your units.  The area of each flat face is (cm) times (cm),
and that product will be some cm² , for area.

Car A used 40.5 L of gasoline to travel 450 km. Car B used 18.7 L to travel 220 km. Circle the car with better fuel mileage. Jus
kvasek [131]

Answer:

Car B has the better fuel economy.

Step-by-step explanation:

Calculate the fuel consumption for the two cars:

Car A:  (450 km) / (40.5 L) = 1.11 km per L

Car B:  (220 km) / (18.7 L) = 1.18 km per L

Car B goes further on one L of gasoline than Car A.
