Paula cut ribbon from a spool for a craft project. each piece of ribbon changed the length of the ribbon remaining on the spill by-1.2 feet. when paula finished, the length of ribbon on the spool had changed by-9 3/5 feet. how many pieces of ribbon did paula cut?

8 pieces

Step-by-step explanation:

Since the spool lost 9 3/5 feet from cutting and it lost 1.2 each cut, then

÷ 1.2 = 8 pieces.

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3
