The table you drew under the question is exactly the right way to start.
-- Make a second column, next to the 6 and 7. This column will be
the actual number of each thing.
-- You know that there are 42 marbles, so write '42' in the box
next to the 6, on the 'Marbles' line.
Now you need to figure out what to write in the 'Stones' line, next to the 7.
-- Look at the 'Marbles' line. There's a 6 and then a 42.
Ask yourself: " Self ! What does the 6 have to be multiplied with to get 42 ?"
-- Whatever the answer is, drop down to the 'Stones' line,
and multiply the 7 by the same number.
The product is the total number of stones, and it goes in the box.

(The mystery number is 7. There are 49 stones.)
x = 7
y = 8
All I did was assume x was 7 and y was 8. I added 4, 6, 7, 8, and 10 together. I got 35. Then, I divided by five (since that's how many numbers are shown) and I got 7 for the mean. 7 is the median, and the 7 is the mean gotten from 4, 6, 7, 8, and 10. Therefore, x must equal 7 and y must equal 8.
Hi there!
The formula for a square is V = s^3. Using this formula, we can plug in the volume and solve for s.
WORK:
343 = s^3
s = 7
ANSWER:
The side length of a cube with volume 343 is 7 inches.
Hope this helps!! :)

Answer:
Your answer is 17.5
Step-by-step explanation:
Turn your fraction into a decimal
2/5 = 0.4
Next multiply my given answer by 0.4
17.5 x 0.4 = 7
