I think what you're looking for is the 3 x 3 "magic square".
It looks like this:
[ 8 ] [ 1 ] [ 6 ]
[ 3 ] [ 5 ] [ 7 ]
[ 4 ] [ 9 ] [ 2 ]
Every row, column, and diagonal adds up to 15.
To solve a 3x3 magic square with decimals, you need to ensure that the sum of numbers in each row, column, and diagonal is equal. Start by placing the decimal numbers in a way that each row, column, and diagonal sums up to the same value. Adjust the numbers carefully to achieve a valid solution.
Factor it! Set each equal to zero! Solve
There are 18 total molecules in 3Be2Br. This is because the subscript numbers indicate how many of each atom are present in the compound. So in 3Be2Br, there are 3 molecules of Be and 6 molecules of Br, for a total of 18 molecules.
15 and 15
You set the two equations equal to each other and then solve for the variable.
Yes, and even more than that: equal numbers of each kindof atoms.
The two numbers that times eachother to equal to 63 are 9 and 7........... (9x7=63)
56
I believe it would be both numbers or none at all.
Compare numbers.
No - the two numbers are equal to each other.
Set each factor, in turn, equal to zero and solve for x.
