Liam has a bag of b beads. He gives 20 beads to his sister. He then makes 4 necklaces with the same of beads on each necklace using all of the remaining beads. Write an expression that represents the number of beads on each necklace. Show your work. * Tip: Use this symbol (/) to show division

(b-20)/4

Step-by-step explanation:

She had b beads initially and gave 20 to his sister;

what he would have now will be;

b - 20

So he made 4 beads with the remaining

To know the number of beads on each of the four , that will be dividing the number of beads we have left by 4

Mathematically;

that will be ;

(b-20)/4

(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

answer: i think one of the answer is $150 and $300?
