2x = 8 so x = 8/2 = 4
or
3x = 12
x = 12/3
x = 4
answer: x = 4 (answer is your last choice)
Answer:
Step-by-step explanation:
I don't see any information on dimensions of the cans or box, so I'll assume the question wants a general solution.
Three steps will result in the volume of sand required to fill the remaining space in the box.
1. Calculate the volume of a can using the equation for the volume of a cylinder: Vol = πr²h
2. Multiply the can volume by 12. This will give the total volume of the 12 cans in the box.
3. Calculate the volume of the box: Volume = (Base)(Width)(Height)
[Make sure the units are the same as those used in calculating the can volume. E.g., if the can is calculated with cm as the measue, the box dimensions must also be cm]
4. Subtract the volume of the12 cans (from step 2) from the volume of the box.
The result from 4 will be the volume of sand required to fill the box containing 12 cans.
I'm not clear why filling the box with sand is important, but perhaps it will absorb any soda released from cans broken when the heavy box is dropped by the person shocked that 12 cans of pop could be so heavy.
Answer:
I believe its A im not exactly sure though
Not sure if the math is correct but I think that it is $199.5
After 150 miles, Beth will have used 150x 1/30 = 5 gallons, which leaves 10 gallons remaining in the tank.After 150 miles, Darcy will have used 150x 1/25 = 6 gallons, which leaves 10 gallons remaining in the tank. Meaning they will have the same number of gallons left at 150 miles
