Answer:

(-7)∧-1

Step-by-step explanation:

(-7)^3 / (-7)^4  

taking each and simplifing it

-7³ = -7 x -7 x -7

(-7)∧4 = -7 x -7 x -7 x -7

(-7)^3 / (-7)^4  = (-7 x -7 x -7 ) / ( -7 x -7 x -7 x -7) = 1/-7

1/-7 ( 1/ means raise to power -1)

1/-7 = (-7)∧-1

Liam has a points card for a movie theater.
ra1l [238]

The  number of visits Liam can make to earn his first free movie ticket is: 8.4.

<h3>Number of visits Liam can make</h3>

Let x represent the number of visits

Formula
55+12.5×x=160

Re-arrange

12.5x=160-55

12.5x=105

Divide both side by 12.5x

x=105/12.5

x=8.4 visits

Therefore the  number of visits Liam can make to earn his first free movie ticket is: 8.4.
