Answer:
x = 8
Step-by-step explanation:
The triangle is isosceles with legs congruent, both x
Using Pythagoras identity in the right triangle
x² + x² = 16²
2x² = 256 ( divide both sides by 2 )
x² = 128 ( take the square root of both sides )
x = 
= 
= 
× = 8
Answer:
A. x + y = 4000
5x + 3y = 15000
Step-by-step explanation:
Total amount raised = $15000
cost of adult tickets = $5
cost of student tickets = $3
Total number of tickets sold = 4000
number of adult tickets sold = x
number of student tickets sold = y
Then we can say,
total number of ticket sold = number of adult tickets + number of student tickets
4000 = x + y
⇒ x + y = 4000 ............. 1
Also,
5x + 3y - 15000 ............. 2
the equations required are:
x + y = 4000
5x + 3y - 15000
