let a be directly proportional to m and n^2, and inversely proprotional to y^3. if a =9 when m=16, n=9 and y=3, find a when m=7, n=4, and y=5

answer

a the answer hopes this

step-by-step explanation:

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

idk

step-by-step explanation:

payback

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
