To get this you substitute 7 for the x.
7/8(7)-1/2
49/8-1/2
49/8-4/8
45/8 is the value.
If you would like to write and solve a system of equations that represent the situation above, you can do this using the following steps:
s ... number of songs
m ... number of movies
$55.00 = $1.25 * s + $2.75 * m
55 = 1.25 * s + 2.75 * m
26 songs and movies = s + m
26 = s + m
s = 26 - m
55 = 1.25 * s + 2.75 * m
55 = 1.25 * (26 - m) + 2.75 * m
55 = 1.25 * 26 - 1.25 * m + 2.75 * m
55 - 32.5 = 1.5 * m
22.5 = 1.5 * m
m = 22.5 / 1.5 = 15 movies
s = 26 - m = 26 - 15 = 11 songs
The correct result would be 15 movies and 11 songs.
94 seats
There are 2 ways to do this one:
1. 18 x 3 = 54
54 + 40 = 94
2. 40 + 3 + 3 + 3.... and so on.

Answer:
Amir: 2/3
Whitney: 1/4
Step-by-step explanation:
We can let w represent the fraction Whitney eats. Then the fraction Amir eats is (w+5/12). The total amount they eat is found by ...
w + (w +5/12) + 1/12 = 1
2w = 1/2 . . . . . subtract 6/12
w = 1/4 . . . . fraction Whitney eats
w+5/12 = 3/12 +5/12 = 8/12 = 2/3 . . . . fraction Amir eats
