Answer:
1394
Step-by-step explanation:
Set up equation to find the number:
Variable n = number
65/100 = 1105/n
Cross multiply:
65 × n = 100 × 1105
65n = 110,500
n = 1700
Check your work:
1700 × 65%
Convert percentage into decimal:
1700 × 0.65
1105
Correct!
Find 82% of 1700:
Variable x = 82% of 1700
82/100 = x/1700
82 × 1700 = 100 × x
139,400 = 100x
1394 = x
Check your work:
1700 × 82%
1700 × 0.82
1394
Correct!
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?"

Answer:
49
Step-by-step explanation:
Every time you multiply both sides of a rectangle by a number x, its area if multiplied by
.
In our example:
Area of a rectangle = width . length
width = 4
length = 7
= 4 . 7 = 28
When you multiply both sides by 7:
width = 4 . 7 = 28
length = 7 . 7 = 49
= 28 . 49
= 1372
/
= 1372 / 28 = 49 = 
Both sides multiplied by 7 => Area multiplied by 
Got it?
