<human>:  Michelle uses 40 beads in making a necklace. She uses 5 blue beads and 2 times as many red beads as blue beads. Then she uses the same number of white beads as the blue and red beads combined. If the rest of the beads she uses are silver, how many silver beads does she use?
<bot>: How many red beads does Michelle use? ** Michelle uses 5 x 2 = <<5*2=10>>10 red beads.
How many white beads does Michelle use? ** She uses 5 + 10 = <<5+10=15>>15 white beads.
How many beads does Michelle use? ** So she uses a total of 5 + 10 + 15 = <<5+10+15=30>>30 blue, red, and white beads.
How many silver beads does Michelle use? ** Therefore, she uses 40 - 30 = <<40-30=10>>10 silver beads.
