Answer:
$ 1 , 150
Step-by-step explanation:
18 chocolate cakes were made. 40(3)= 120 cakes in total. 15%=.15 .15(120)= 18
Because the 18-gon is symmetrical, you can rotate it by 360/18 or 20 degrees. This is because when you rotate it by 20 degrees(to the left for explanation matters), any angle will now be in the position of its angle to its left.
2(11 + 3x) = 64
11 + 3x =64/2
11 + 3x = 32
3x = 32 - 11
3x = 21
x = 21/3
x = 7
