For the fulcrum to balance, the product of weight and distance on both sides of the fulcrum must be the same.
Let d1= x. since total distance is 12, we can write d2 = 12 - x
for the fulcrum to balance:
60x = 50(12 - x)
60x = 600 - 50x
110x = 600
x = 5.45
Thus, d1= 5.45
and
d2= 12 - d1 = 12 - 5.45 = 6.55
d1 = 5.45
d2 = 6.55
Answer:
Step-by-step explanation:
Answer:
the book has 64 pages
Step-by-step explanation:
denoting the number of pages of the book as X then
number of pages read on Monday + number of pages read on Tuesday + number of pages read on Wednesday = number of pages of the book
40 + 1/8*X + 1/4*X = X
40 + 3/8*X = X
40 = X - 3/8*X = 5/8*X
X = 40*8/5 = 64 pages
therefore the book has 64 pages
