Answer:
7.5 pounds.
Step-by-step explanation:
the answer is 7.5 ponds because if each slider has 2 oz. then we can find the total number of oz. needed by multiplying by 60. This gets 120 oz that Scarlett needs in total. Since there are 16oz in a pound we divide 120 by 16 to find the number of pounds needed.
Perimeter is 2L + 2W
Now plugging in for values we know
42=2L + 2(7)
Move the 14 to the other side to isolate the variable L
28=2L
Divide by 2
L= 14 feet
L is length
