Answer:
First number = 33, Second number = -19
Step-by-step explanation:
We can use F to represent the first number and S to represent the second number.
Our two equations then are F + S = 14 and 2F + 3S = 9
We can use substitution:

0.7 is the answer, I will not explain or you as you should figure that out.
Percent change is
(New - old) / old
50 - 75 / 75
25 / 75 = .33333333....
To convert to a percent, multiply by 100
Percent decrease = 33.33%
Answer:
-9, -8.2, -4, 6, 1 3/4
Step-by-step explanation:
The larger the number is if it's a negative, the lower it is (if that makes sense). For example, -9 is lower than -7.
1 3/4 = 1.75
