Respuesta :

so, let's just call x the number of beads that are needed to make a bracelet.

now, how many beads does it take to make a necklace?

"It takes 5 times as many beads to make a necklace than it does to make a bracelet. '

What does it mean? five times: 5x

so it takes 5x to make a necklace

she also used 192 to make a necklace and a bracelet.

that means: x (bracelet) +5x(necklace)=192
x+5x=192
6x=192

now we divide by 6:

x=32

so it takes 32 beads to make a bracelet and 5 times as many, 5*32=160 to make a necklace
