A-students taking band
B-students taking chorus
|AuB| = 250
|A| = 180
[AnB] = 60
|AuB| = |A| + |B| - |AnB|
|B| = |AuB| - |A| + |AnB| = 250 - 180 + 60 = 130
ans: 130 students in chorus only
Answer:
<u>x = 5</u>
Step-by-step explanation:
Both angles add to 180, so by knowing that we can say...
16x - 5 + -5 + 22x = 180
Now simplify and solve
38x - 10 = 180
38x = 190
<u>x = 5</u>
You might be referring to decimal places
260 is the correct answer because 65 is twenty percent of 260
