Answer:
Step-by-step explanation:
Starting with 2x+6=22
You subtract 6 from each side of the equation:
2x=16
You want to isolate the "x" so you divide each side by 2.
x = 8
check your answer: 2x + 6 = 22
2(8) + 6 = 22
16 + 6 = 22
# of students who wore red = 150
# of students who did not wear red = 250
Total #. of students = 150 + 250
= 400
Percentage of students who wore red =
(# of students who wore red/Total #) * 100 = (150/400) * 100 = 37.5
∴ No of students who wore red = 37.5%
