Answer:
Let us assume the total number of students surveyed = x
Then
Number of students preferring red = x/4
Number of students preferring blue = x/8
Then
Number of students remaining = x - [(x/4) + (x/8)]
=x - [(2x + x)/8)
= x - (3x/8)
= (8x - 3x)/8
= 5x/8
Number of students preferring the color green = (3/5) * (5x/8)
= 3x/8
We also know that the total number of students preferring the color green is 15
So
3x/8 = 15
3x = 15 * 8
x = (15 * 8)/3
= 5 * 8
= 40
So in total 40 students were surveyed. I hope the procedure is clear to you.

Answer:
the length and width
Step-by-step explanation:
to find area, the eqaution is length times width
Answer: D. 453 miles .
Step-by-step explanation:
Given: The function 
models the distance, in miles, that Jessica is from her house <em>t </em>hours after she began returning home.
At t = 5 minutes = 
hour [1 hour = 60 minutes],
Distance covered by Jessica in 5 minutes = 
Jessica is 453 miles from her home after 5 minutes she began returning home.
Hence, the correct option is D. 453 miles .
3x^2 + 180x - (3x^2 - 160x + 300) = profit
3x^2 + 180x - 3x^2 + 160x - 300 = profit
340x - 300 = profit
so if 150 televisions are sold...x = 150
340(150) - 300 =
50,700 <==
