Answer: the number of students that were surveyed is 40
Step-by-step explanation:
Let x = total number of students that were surveyed about their favorite colors
1/4 of the students preferred red.
This means that the number of students that preferred red is 1/4 × x = x/4
1/8 of the students preferred blue.
This means that the number of students that preferred blue is 1/8 × x = x/8
The remaining number of students will be the total number of students - the sum of the number of students that preferred red and the number of students that preferred blue. It becomes
x - (x/4 + x/8) = x - 3x/8 = 5x/8
3/5 of the remaining students were for green. This means that the number of students that preferred green is 3/5 × 5x/8 = 3x/8
if 15 students prefer green, then
3x/8 = 15
3x = 120
x = 120/3 = 40 students
1.3 x 10^1
hope that helped
let me know if i am right please
I'd say Isaiah Canaan or Kevin Love, Isaiah has quick reflexes and can keep up with the pace of the game, Kevin is basically assurance for anyone that they can land in the greenzone

Answer:
x = -1
Step-by-step explanation:
-2(x - 5) = 12
-2x + 10 = 12 (this is the mistake, -2 times -5 = + 10)
-2x = 12 - 10
-2x = 2
x = 2/(-2)
x = -1
