a) Prom allows people to buy tickets for singles or couples. The
total number of people at the dance was 130. Single tickets cost
$40 and couples tickets cost $75 and there was a total of $4950
in ticket sales. How many singles and couples tickets were sold?
i)Define variables (what unknowns is being solved for)

ii)Write an equation based on each constraint/info.
total cost = cost of single tickets + cost of couple tickets
# of people = single people + couples people

iii)Solve the system above

iv) Write a sentence that answers the question.

Step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
