Answer:
Julie's bill came to $121 for the month in which she ordered 12 movies.
Step-by-step explanation:
Let x represent the number of movies ordered.
Julie: $70 + ($4.25/movie)x, and ...
Tim: $49.50 + ($5.50/movie)x
If Julie ordered 12 movies last month, then her bill came to
$70 + ($4.25/movie)(12 movies) = $70 + $51 = $121
Please be clearer about what you want here. Are you refering to Julie or to Tim or to both when you write, "an equation that best represents the amount of movies?"
Sum of internal angles on same side of transversal is 180
(8x-14) +(2x+54) =180
10x +40 =180
10x =140
x=14
option D x=14 is correct
Use the Pythagorean theorem:
Height is 14, base is 3, so we can calculate the length required.
Length = sqrt(14^2 + 3^2)
Length = sqrt( 196 + 9)
Length = sqrt(205)
Length = 14.32 feet.
The ladder needs to be 14.32 feet. The longest her ladder can be is 14 feet so her ladder won’t work.
