Li is making beaded necklaces. for each necklace, she uses 25 spacers, plus 3 beads per inch of necklace length. write an equation to find how many beads li needs for each necklace, where x is the length, in inches, of the necklace. the equation that represents this situation is y =

y = 3x

Step-by-step explanation:

Li is making beaded necklaces where he uses 3 beads per inch of the necklace length.

We have to write an equation to find the number of beads that Li needs for each necklace, where x is the length, in inches, of the necklace.  

Hence, we can write the equation for number of beads as y = 3x ( Answer )
