Let the smaller number be x
let the larger number be y
According to Question-
x + y = 2y - 4
→ x - y = -4 ...1
if larger number is decreased by 1/3 we get equation -
x + y/3 = -20
→ 3x + y = -60 ...2
adding equation 1 and 2, we get:
4x = -64
→ x = -16
→ y = -60 - 3(-16)
→ y = -60 + 48
→ y = -12
Answer:
The number of days are independent and the total number of minutes are dependent.
The required model for the situation is 
The table is shown below:
Step-by-step explanation:
Consider the provided information.
Joshua spends 25 minutes of each day reading. Let d be the number of days that he reads, and let m represent the total minutes of reading.
We need to determine which variable is independent and which is dependent.
Here, the number of days are independent and the total number of minutes are dependent.
If he spends 25 minutes each day. So the total number of minutes in d days are:

The required model for the situation is 
Now make the table which showing the number of minutes spent reading over 7 days.
Substitute the value of d from 1 to 7 in 
Number of days(D) Minutes(M)
1 25
2 50
3 75
4 100
5 125
6 150
7 175

Step-by-step explanation:
13) (x+3)+49=180
14) 66+8x=90
15) (x+3)+49=90
16) 3x+117=180
7/9-1/3 or 7/9-3/9= 4/9 is the answer
