Drew and Larry are working together on a jigsaw puzzle. Drew places 11 less than 3 times the number of pieces that Larry places. Drew places at least 10 pieces. How many pieces does Larry place?

Larry places 19 puzzles

Step-by-step explanation:

Step one:

given data

let the number of puzzles Larry places be x

and let the number of puzzles Drew places be y

so

y=3x-11

Step two:

We are told that Drew places at least 10

so for x= 10

y= 3*10-11

y=30-11

y=19

b) the dogs need to shift their focus to human scent.
