Answer:
15 students celebrate both holidays
Step-by-step explanation:
Let the number of students that celebrate both be x
By set notation, we add up individual sides as follows to give the number of values on the universal set
Mathematically, that will be;
50 = (29-x) + (36-x) + x
50 = 29-x + 36-x + x
50 = 65-x
x = 65-50
x = 15
Answer:
2 a. x= -2, x=10 2 b. x= -7, x=7
Step-by-step explanation:
move the -6 to the left to get
-7 x lx-4l = -42
divide both sides of the equation by -7
lx-4l = 6
separate into
x-4=6 and x-4= -6
solve by adding 4 to both sides
then on the other one add 4 to both sides
2b you do the same steps just different numbers
