Answer:
A=6e2==6e2
e==6
e2A==6e2
Step-by-step explanation:
5b is 12-b=13 first you have to subtract 12 from both sides and you get -b = 13-12 which then gives you -b=1 then you have to divide both sides by -1 and you get 1/-1 which gives you b=-1
Answer:
13 days
Step-by-step explanation:
Amount of book left = 100% - 35% = 65%
If 35% requires 7 days,
65% requires x days.
Using the 'cross the heart' or 'cross multiplication' method:
35x = 7 * 65
x = (7 * 65)/35
= 455/35
= 13
Hence, it would take 13 more days to complete the book.
