Answer:

w= 15.75 or 15 3/4

Step-by-step explanation:

So I would multiply 100 on both sides to get rid of the decimals so I’d end up with 40w+245=875

Now solve it by subtracting 245 on both sides.

40w=630

now divided 40 on both sides

15 3/4

Final answer 15 3/4 or 15.75

(200 cm)/(10 cm/section) = 20 sections

that can be cut from the pipe.
