When Dylan checks their school lunch account, the balance is $56.
After buying 8 lunches, the balance is $40.
At Dylan's school, every student starts with a balance
of $80 for school lunches.
How many lunches had Dylan bought when they first
checked their balance?

12

Step-by-step explanation:

80-56=24

16/8=2

24/2=12

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
