You need Pythagorean theorem for this.
a² + b² = c², where c is the hypotheneus and a and b are the sides of the right triangle.
24² + x² = 26²
x² = 676-576
x = ±√100
x = 10 (-10 is rejected because length of triangle cannot be a negative number)
(Change)/(original) *100
.05/2.87 *100
1.7%
570
600×0.95 = 570
I did this because if they made a 5% profit them you substrate that from 100 and divide the original price from what you get.
The system of equations does not have a solution.
For example, imagine these two equations y = x + 7 and y = x + 9
Now subsitute y in the second equation with the value from the first equation:
x + 7 = x + 9
x - x + 7 = 9
0 + 7 = 9
7 = 9.
That happens because the equations represent parallel lines, which do not have a common pair of points.
The horizontal distance between AC is 15 units
The vertical distance between AC is 7 units
The point B is located such that AB: BC = 5:2, in other words, AB = 5/7 of the line and BC is 2/7 of the line
5/7 of the horizontal distance is (5/7) × 15 = 75/7
2/7 of the vertical distance is (2/7) × 15 = 30/7
The coordinate of B is (75/7, 30/7)
