Answer:
44 cubic meters
Step-by-step explanation
9 + 4 + 6 = 19
9/19 of the patio will be cement
4/19 of the patio will be gravel
6/19 of the patio will be stones
Work out the amount of gravel - 4/19 * 209 = 44 cubic meters

I think you meant to write 2* 69
X is confusing
But I think you meant multiplication problem so the answer is
2 times 69 = 138
Might be wrong haven't done algebra for years but i think it is 7-9n/7
I got that x=-5.37003947. I am not sure that I put everything under the square root that needed to be there so I hope this helps.
