Solve P = 2 (l + w) for w. w =

To solve for w, you need to isolate/get the variable "w" by itself in the equation:

P = 2(l + w)     Divide 2 on both sides

    Subtract l on both sides to get "w" by itself

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
