At friday's football game, 1294 tickets were sold for a total amount of $8,816.00 . if each student ticket costs $5.00,and each adult ticket costs $8.00, how many student tickets were purchased?

x = # of student tickets

y = # of adult tickets

x + y = 1294 >> y = 1294 - x

5x + 8y = 8816

5x + 8y = 8816

5x + 8(1294 - x) = 8816

5x + 10,352 - 8x = 8816

-3x + 10,352 = 8816

-3x = -1536

x = 512 student tickets

512 student tickets were purchased.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
