Same. If you change both side with same value, it keeps the equality.
It'll be 19 because your just adding numbers
0.8x=16
then x=16/0.8=20
therefore Karen takes 20 minutes to walk to school
Let us say that:
x = number of students who are members.
Since both groups went together to the planetarium, therefore this means
that 19-x is the number of students who are not member
Since x paid $11 for tickets and (19-x) paid $13 so the total cost of
the tickets is:
$11x + $13(19-x) = $209
Solving for x would get us the number of members:
11x + 247 – 13x = 209
-2x = -38
x = 19
<span>Therefore this means that all students are members.</span>
