Answer:
There were 10 flies originally
Step-by-step explanation:
Since we have an exponential growth, we will be having a constant percentage of increase and we can set up the increase at any day using the following equation;
V = I(1+r)^d
where V is the number of flies on a particular day
I is the initial number of flies
r is the constant increase in percentage
and d is the number of days.
So we have for the second day;
60 = I(1+r)^2 ••••••(i)
For the fourth day, we have;
360 = I(1+r)^4 ••••••••(ii)
divide equation ii by i; we have;
360/60 = (1+r)^4/(1+r)^2
6 = (1+r)^2
(√6)^2 = (1+r)^2
1 + r = √6
r = √6 - 1
So we can substitute the value of r in any of the equations to get I which is the initial number of flies
Let’s use equation 1
60 = I(1 + r)^2
60 = I(1 + √6 -1)^2
60 = I(√6)^2
60 = 6I
I = 60/6
I = 10 flies
Answer:
6-2y=4y+8
since you show x through y
Answer:
The result that is obtained on comparing the system of equations in order to get the solution to the system of equations is:
6 -2y =4y + 8
Step-by-step explanation:
We are given a system of equations in term of variable x and y as follows:
x + 2y = 6 --------(1)
x - 4y = 8-------------(2)
From equation (1) we have the value of x in terms of y as:
x=6-2y
From equation (2) we have the value of x in terms of y as:
x=8+2y
Hence, on equation the above two values of 'x' we obtain:
6 - 2y = 4y + 8

The ratio of number of fiction books to total number of books that she read 12:13.
Given :
Emily reads 24 friction books and 2 nonfiction books.
Number of fiction books she read =24
Number of nofiction boos she read = 2
Total number of books = 26
To Find :
What is the ratio of the number of fiction books she read to the total number of books that she read ?
Solution :
Total number of books that she read=24+2=26
number of fiction books she read=24
Thus ratio of number of fiction books to total number of books that she read
⇒ 
⇒ 
⇒ 12: 13
Hence ratio of number of fiction books to total number of books that she read 12 : 13
