For the graffiti cat sweater, Dodd knit 12 stitches to make 2 inches in width. The sweater is 9 inches wide from the left edge to the beginning of the black smile. How many stitches wide is that?

  54 stitches

Step-by-step explanation:

Dodd's knitting is (12 stitches)/(2 inches) = 6 stitches per inch. Then in a width of 9 inches, there will be ...

  (9 inches)(6 stitches/inch) = 54 stitches

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
