Answer:
Lucy sews
dresses in 1 hour.
Step-by-step explanation:
Given:
Lucy sews
of a dress in
hour.
She sews at constant rate.
We need to find the number of dresses she makes in 1 hour.
In
hour =
dress
So in 1 hour = Number of dresses in 1 hour
By using Unitary method we get;
Number of dresses in 1 hour= 
Hence Lucy sews
dresses in 1 hour.
The ratio of cats to all animals is 12:23.
Luckily for us, this problem solved the bulk of its own question!
Now, all we have to do is solve for "x", or the amount of fiction books and plug its value back into the original equation to find the value of "y", or the amount of nonfiction books.
2x = 38
x = 19
There are 19 fiction books.
x + y = 26
19 + y = 26
y = 7
There are 7 nonfiction books.
Hope this helps!
