What is 12 = 1 + a/1 -a?

a = 11/13

Step-by-step explanation:

Multiply both sides by 1 - a

12(1 - a) = 1 + a

= 12 - 12a = 1 + a

Subtract 12 from both sides

= -12a = -11 + a

Subtract a from both side

-13a = -11

Divide by -13 each side

-13a/13 = -11/-13

= a = 11/13

correct answer:

i^31 = -i

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
