Look at it this way:
-- Since the two groups have the ratio of 4 to 7, then the first group has 4 parts
and the other group has 7 parts.
-- If the first group has 4 parts and the other group has 7 parts, then they have
11 parts all together.
-- Those 11 parts are all parts of 33. There must be ( 33 / 11 ) = 3 items in each part.
Now you can go back to the groups . . .
-- The first group has 4 parts.
With 3 items in each part, that's (4 x 3) = 12 items.
-- The other group has 7 parts.
With 3 items in each part, that's (7 x 3) = 21 items.
The number of books she would have completed in one day will be 2 books.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
Given that:-
Emily completed reading 24/3 books in 32/4 days
Emily completed 8 books in 4 days. The number of the books will be calculated by using the expression below:-
4 days = 8 books
1 day = 8 / 4 = 2 books
Therefore the number of books she would have completed in one day will be 2 books.

It’s supposed to be (5,9) both numbers positive
Answer:
choice 1) 2-4y
Step-by-step explanation:
from the answers available, you are looking for the expression for x to substitute into the first equation.
The second equation is: x+4y = 2
To convert x+4y = 2
subtract 4y from both sides of the equation:
x+4y-4y = 2-4y
simplified:
x = 2-4y
The answer is J.
11+2=13
13+3=16
11+7=18
11+17=27
