The Student Council is selling tickets to the Fall Dance. Tickets cost $5 per person or $8 per couple. To cover expenses, at least $1200 worth of tickets must be sold. No more than 500 students can fit in the gym where the dance is being held. Let x = number of $5 tickets

Let y = number of $8 tickets

write a system of inequalities to represent this situation.

plot a point to show a solution to the system of inequalities you wrote

Write numerical coefficient of y² in the expression 2x² - 15xy – 7y²

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)

Ateacher noticed 5/8 of the students were wearing either blue shorts or white shorts. write two different ways this could be done.
