This isn't too bad. When a question asks for a negative plus a negative, just think of it as the negative minus a negative. -3-17. When you subtract two negatives, it's kinda like asking for adding two positives. The answer will be 20, not 14 as lots of folks mistake this part.

Now that we know -3-17, we have to add 13. This is adding a positive to a negative, so it's subtraction. -20+13. Same as asking 13-20. Which is -7.

Final answer: -7

(?,5) is on the line 4x-7y=1. Find the other half of the coordinate.

ludmilkaskok [199]

The coordinate is an ordered pair $(x,y)$ . We have a number, 5, for y, which we can substitute (plug-in) for y in the equation of the line and solve for x.

$4x-7y=1\\4x-7(5)=1\\4x=36\\x=9$

What is the relationship between the magic constant (the sum of each row) and the sum of all the numbers in the square? Why does

NARA [144]

Let's say each row sums to 15

If we had 3 rows, then the total sum would be 3*15 = 45

If we added all of the values in the 3x3 magic square, then we'd get 45 as well.

This is one example showing that

sum of all values = (number of rows)*(magic constant)

You can replace "rows" with columns to get the same idea, because each column also adds to the same magic constant. The diagonals are an exception since we only have two of them.
