Pythagorean Theorem:
a^2 + b^2 = c^2
Since you have the hypotenuse, you can change the equation to find the missing side.
a^2 - c^2 = - b^2
Insert your numbers:
9^2 - 10^2 = -b^2
What do you get?
First or the second idk what the red filling is supposed to be...
2x + 1.5 y = 985
y = students
x = adults
x + y = 578
*-2 * -2
-2x - 2y = -1156
2x + 1.5y = 958
-2x - 2y = -1156 (add these together)
-0.5 y = -198
*-2 *-2
y = 396
x + 396 = 578
x = 182
396 students
182 adults
