Answer:
4 students
Step-by-step explanation:
As shown in the diagram, let U=[The total number of students questioned]
A=[Those who liked peanut butter ]
B=[Those who liked jam ]
x = those who like both peanut butter and jam.
Also 6 liked neither peanut butter nor jam.
From the diagram we can write the mathematical equation as follow and solve for x
We add x and subtract 30 to both sides.
Therefore 4 students like both peanut butter and jam.
Answer:
(c+3b)/8 = a
Step-by-step explanation:
c = 8a -3b
Add 3b to each side
c +3b = 8a-3b+3b

(c+3b)/8 = 8a/8
(c+3b)/8 = a
