Answer:
11 feet
Step-by-step explanation:
First, convert all the mixed fractions to improper fractions in the a/b form.
4 1/2 becomes 9/2 and 2 1/2 becomes 5/2.
Adding 9/2 to 5/2 we get (9+5)/2, which is 14/2 and that can be simplified to 7.
Finally, adding 7 to 4 we get 11.
So, the sum of the length of all three tables is just 11 feet long.
Hope this helps!

C is the correct answer
Step-by-step explanation:
Answer:
a) 15
b) 2
Step-by-step explanation:
a) The sum of the enrollments in chemistry (60), physics (45), and biology (30) counts those triply enrolled 3 times and those doubly-enrolled twice. This sum will exceed the total number of students by 1 times those double-enrolled and twice those triply-enrolled.
We know that there are 10 students triply-enrolled, so the difference ...
(60 +45 +30) -2(10) = 15
is the number of doubly-enrolled students.
There are 15 students enrolled in exactly 2 science classes.
__
b) There are 9+4 = 13 students doubly-enrolled in physics and something else. Using the result from part A, there will be 15 -13 = 2 students doubly-enrolled in chemistry and biology, but not physics.
