Find the value of x in the figure

I am 99% sure it's °, here's why (down)

Step-by-step explanation:

The total is 180°. When adding 57° + 23° = 80°. To get , you have to subtract 80° from 180°. The difference is 100°, which is the answer of this problem.

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.

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted
