hey mate:-
- hey mate:- A{12,20,21,22,23}
- here number of elements in A= 5
B{18,19,20,21,22}
here number of elements in B= 5
- number of elements in A= number of elements in B= 5
as we know
when number of elements are same
given
- here number of elements in A=here number of elements in B
there fore these are equivalent sets..,,
Answer:
Subtract 23 from both sides

How many turns do they get to take? if it is on round I guess it would get the high number of 8
Answer:
x1 = 1, x2 = 2, x3 = 7
Step-by-step explanation:
(x-2) x (x² -8x + 7) = 0
When the product of factors equals , at least one factor is 0.
x-2=0
x² -8 + 7=0
Solve the equation for X.
x-2=0
x=2
x² -8+7=0
x=7
x=1
The final solutions are
x1 = 1, x2= 2, x3=7
25 students got 2 chaperones
so 1 will get 2/25
and thus 8 will get 2/25×8 = 0.64 chaperone
but is it possible?? No chaperone can not be in decimal so at least 1 is required !!
