Answer:
x=65/n where x is 1 book and n the number of books
Step-by-step explanation:
If n is the number of books, lets say 1 book is "x", then
nx=65
x=65/n
for example
n=1 then x=65
n=2 then x=65/2
n=3 then x=65/3
The mass lost by Darragh's coin is 0.164 g
<u>Solution:</u>
Given that Darragh has a Golden Eagle coin in his collection with a mass of 13.551 g
An uncirculated Golden Eagle coin has a mass of 13.715 g
To find: mass lost by Darragh's coin
From given question,
Darrangh has coin of mass = 13.551 g
Golden Eagle coin mass = 13.715 g
Darrangh's coin lost mass = 13.715 - 13.551 = 0.164
Thus mass lost by Darragh's coin is 0.164 g
Lets list what we know:
1.5 cups = 18 cookies
How many cups in 1 cookie will help us find the answer:
1.5 / 18 (1.5 cups per 18 cookies)
divide both sides by 1.5 (to get how many cookies in 1 cup)
1 / 12 (1 cup = 12 cookies)
Now, how many times does 12 fit in 30?
30/12 = 2.5
This means it takes 2 and a half cups of raisins to get 30 cookies.
