Sausages come in packets of 12. Bread rolls come in packets of 18. Dan wants to buy enough packs of sausages and rolls so that there are an equal number of sausages and rolls. What is the minimum number of sausages and rolls he needs to buy?

3 packages of sausages and 2 packages of bread rolls.

Step-by-step explanation:

3 times 12 is 36

18 times 2 is 36

the answer is 216

Step-by-step explanation:

12 × 18=?

     12

×    18

+    96

+  12  

=  216

Therefore:

12 × 18 = 216

(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

5+2x=a
