Answer:

ALGEBRA: 9

BIOLOGY: 24

STUDENTS:27

Step-by-step explanation:

Since it says  15 are taking biology then there is 9 taking both algebra and biology, so the algebra is 9 then the biology is 24, Adding the 15 who takes biology ang the students who do both algebra and biology that is 9+15= 24

then the students are 27 adding the 9, 24 and the 3 who does not taking their course that equals to 27.

Answer:

hindi ako makasagot sa isa mong post eh, so yung magtatake ng algebra ay 15 at 11 ang biology, ang gagawin mo dahil merong magtatake ng both imiminus mo yung 9 sa 15 at 11

15-9=6

11-9=2

6 ang nagtake ng algebra at 2 ang sa biology

Ang total students ay 11
