Answer:
82
Step-by-step explanation:
3x27=81 so 81 is a multiple of 3
there is no integer x for which 4x=46 so 46 is not a multiple of 4
there is no integer x for which 7x=55 so 55 is not a multiple of 7
72 = 8*9 so 72 is a multiple of 9
there is no integer x for which 6x=45 hence 45 is not a multiple of 6
D. 54° as you know an external angle has to equal up to 360
when you start plugging in 360 by 36 gives you 10
360 by 40 gives you 9
360 by 45 gives you 8
360 by 54 gives you 6.666 repeating you know that it isn't possible
you cannot have a repeating number of sides as an angle measure
that's how you get that answer
5 people x $5 appetizers = $25
5 people x $10 main dish = $50
Total cost for the group of 5 = $75
$75 - 20% (.2) = $15 each person has to pay
Check ur work
$15 x 5 = $75
My answer of the square is 72
