Answer:
The answer should be 6:2.
I am not 100% sure so please make sure to take that into account,
Anyway I hoped this helped

Step-by-step explanation:
One simple way to approach this is to subtract the number that DOESN’T have the variable with the solution by the sum.
Lets use problem 1 as the example:
1.) N+8=13
In this case, we subtract 13 by 8 and get 5, therefore N= 5.
2.) B+17=62
62-17= 45
B= 45
3.) X+5/6= 7/16
7/16-5/6= -19/48
X= -19/48
4.) y+1/7=5/8
5/8-1/7= 27/56
Y= 27/56
5.) 14+y=69
69-14=55
Y=55
6.) c+3.6=4.9
4.9-3.6=1.3
C= 1.3
Now for the word problems:
Lets use 7 as the example-
7.) a number increased by 19 is equal to 221.
Since we don’t know the number being increased by 19, that will be our variable. It will be re-written as so:
N + 19 = 221
Where N is the unknown number.
Using the same method of subtracting by the sum and the number that’s not the variable, we’ll get the solution to N
221-19= 202
N= 202
8.) N + 1 2/3 = 8
8 - 1 2/3 = 19/3= 6 1/3
N= 6 1/3
I really hope this helps
Given:
Granny Apples charge $12 for 6 pounds of apples.
Wilson' Apples charges $15 for 5 pounds of apples.
To find:
Which apple company provides a better deal.
Solution:
We need to compare unit price of both companies.
Unit price of Granny Apples,
Unit price of Wilson Apples,
Since, per unit price of Granny Apples is less than Wilson Apples, therefore Granny Apples provides a better deal.
13 is a prime number so its only factors are 1 and 13
