171 / 7.6 = 22.5 miles per gallon
22.5 x 12.5 = 281.25 miles she can drive
3 x
---------= --------- ---------
15 180
15x=540
----- ------= 36 students.
15 15
Steps: Cross multiply to get 15x and 540. Divide both numbers by 15, then you found what x equals, which is the answer.
Answer:

Step-by-step explanation:
This shape is actually just a rectangle with a missing triangle. We can first find the area of the rectangle with
and subtract the triangle.
Area of missing triangle =
(b is the base and h is the height)
Base = 
Height = 
Area of missing triangle = 
Area of the figure: 
--------------------------------------------------------------------------
Alternatively, you can find the area of each individual shape and add them all up.
Area of the rectangle:
Area of square: 
Area of triangle: 
Total Area: 
The car went about 35.34 miles per gallon.(How? Divide 7.3 into 257 and you got your answer.)
The first answer would be A because the volume is l*w*h so you would multiply 24 by 10 by 12 which gives you 2880 ft^3
I don't know how to do the second question. I am sorry!
