How many adult tickets were sold if each adult ticket sold was $6 and each student ticket was $4.50 and 260 tickets were sold fo

erik [133]

Answer:

Adult tickets sold: 156

Step-by-step explanation:

Adult ticket: x

Student ticket: y

x + y = 260 ===> -6(x + y = 260) ===> -6x -6y = -1560

6x + 4.5y = 1404 ===> 6x + 4.5y = 1404

________________

add the two equations to eliminate a variable: -1.5y = -156

divide by -1.5: y = 104

substitution to find x:

x + y = 260

x + 104 = 260

x = 156

$\frac{(5 - 2) \times 180}{5} = \\$

$\frac{3 \times 18 \times 10}{5} = 3 \times 18 \times 2 = \\$

$54 \times 2 = 108$

Thus each angle has a measure of 108° degrees.
