We know already that desk A and desk B are on the same column, since both coordinates' x factors are 7. So all we need to do now is find the differeance of 2 and -8. So, we get the [very simple] equation 2 - (-8) = d. Now, when you subtract a negative, it's pretty much just adding, so we can simplify this equation to 2 + 8 = d, and we all know 2 + 8 = 10. So the distance between the two desks is 10 units.
Hope this helps! If there is anything wrong feel free to point it out.
Have a nice day!
We have 240/40 = total students/ 100
Total students are in the middle school is: (240 x 100)/ 40 = 600 students

The answer would be A. When using Cramer's Rule to solve a system of equations, if the determinant of the coefficient matrix equals zero and neither numerator determinant is zero, then the system has infinite solutions. It would be hard finding this answer when we use the Cramer's Rule so instead we use the Gauss Elimination. Considering the equations:
x + y = 3 and <span>2x + 2y = 6
Determinant of the equations are </span>
<span>| 1 1 | </span>
<span>| 2 2 | = 0
</span>
the numerator determinants would be
<span>| 3 1 | . .| 1 3 | </span>
<span>| 6 2 | = | 2 6 | = 0.
Executing Gauss Elimination, any two numbers, whose sum is 3, would satisfy the given system. F</span>or instance (3, 0), <span>(2, 1) and (4, -1). Therefore, it would have infinitely many solutions. </span>
