In a group of 60 students, 12 students take algebra 1, 18 students take algebra 2, and 8 students take both subjects. how many students don't take either of these subjects?

38

Step-by-step explanation:

First create a 2 circle venn diagram. Then insert what both subjects have in common- 8 students. From there calculate how many students are in algebra 1 and 2 while acknowledging the 8 students shared. Thus algebra 1 will contain 4 students in its circle because 8+4=12 and algebra 2 will contain 10 students because 8+10=18. Your final steps would be to add the values in the venn diagram- 4+8+10=22 and subtract that sum by the "sample space"/ total students to get 38. :)

the least common denominator is 40

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
