Answer:
Step-by-step explanation:
Tracey Earns in week= $102.45
Tracy=2x-12.45
102.45=2x-12.45
2x= 102.45+12.45
2x=114.90
x= 114.90/2
x=$57.45
Kayla earns 57.45 dollars
1 feet equals 12 inches

Answer:
6.67 ft
Step-by-step explanation:
Let d = distance
and w = weight
Then d = k/w
or dw = k
Let d1 and w1 represent Roger
and d2 and w2 represent Ellen. Then
d1w1 = d2w2
Data:
d1 = 6 ft; w1 = 120 lb
d2 = ? ; w2 = 108 lb
Calculation:
6 × 120 = 108d2
720 = 108d2
d2 = 720/108 = 6.67 ft
Ellen must sit 6.67 ft from the fulcrum.
