2.P. S. 89 is having an ice cream social for the graduating 8th grader a
Ms. Gallo has to order the ice cream. She decided to order 21 cartons of vanilla ice cream and 28 cartons of
chocolate ice cream. Let V to represent cost of the vanilla ice cream and C to represent the chocolate ice cream.
Write an algebraic expression that represents the total cost of buying the ice cream
B
Write an equivalent expression for your answer in part (a).
С
Explain why the expressions are equivalent

55% are girls and 45% are boys : ) hope this

step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
