Let A= adult tickets and S= student tickets
A+S=148
9A+6S=1,188
You can plug into a calculator or by hand is shown below
-6(A+S)=-6(148) Checking the answer
-6A-6S=-888 A=100
+ 100+S=148
9A+6S=1,188 S=48
——————— 9(100)+6(S)=1,188
3A+0S=300 900+6S=1,188
1/3(3A)=1/3(300) 6S=288
A=100 S=48
And to check is on the right side
Total Weight = Weight of the book + Weight of the CD + Weight of the box
Total Weight = 1 1/4 pound + 1/5 pound + 3/10 pound
Total Weight = 5/4 + 1/5 + 3/10
To add these fractions, you need to put them over a common denominator. To do that, find the least common multiple of 4, 5, and 10. Below is a table of the multiples. The least multiple they have in common is 20, shown in orange. So use 20 as your least common denominator.
1 2 3 4 5 6 7
4 x 4 8 12 16 20 24 ...
5 x 5 10 15 20 25 30 ...
10 x 10 20 30 40 50 60 ...

Step-by-step explanation:
Answer:
the four point cannot be on the same line , but they have to be on the plane.
A D C E
collinear means on the same line
so ABC
non-coplanar means the point do not lie on the same plane so you can include point F
F A D B
5/6 is closest to 1 because it it 1/6 away from 1 and is 5/6 away from 0 and is 2/6 away from 1/2 (referring 1/2 as 3/6) Hope this helps!
