<u><em>First, we need to get the amount of change:</em></u>The amount of change can either be an increase or a decrease.
It can be calculated as follows:
amount of change = </span>
<span>
If the amount of change is positive, then it is an increase
If the amount of change is negative, then it is a decrease
<u><em>Then, we need to convert this amount into a percentage:</em></u>Changing the amount into a percentage can simply be done by multiplying this amount by 100
This means that:
% of change = amount of change * 100
<u><em>Combining the two steps:</em></u>% of change = </span>
<span> * 100
<u>Examples:</u>The original price of a certain product was $10. It then became $12. Find the % of increase.
% of change = </span>
<span> = 20%
This means that the price increased by 20%
The temperature decreased from 25 degrees to 20 degrees. Find the percentage of decrease.
% of decrease = </span>
<span> = -20%
This means that the temperature decreased by 20%
Hope this helps :)</span>

Answer:
For the given expression:
Step-by-step explanation:
Here, the given expression in statement form is given as:
5 X minus Y equals 6 + negative 2 X plus Y = 8
Now, converting the given statement mathematically, we get:
5X - Y = 6 + (-2X) + Y = 8
Now, considering first and the last terms,we get:
5 X - Y = 8 .... (1)
and , considering second and the last terms,we get:
6 + (-2X) + Y = 8 or, -2X + Y = 2 ......... (2)
Adding (1) and (2) , we get:
5 X - Y - 2 X + Y = 8 + 2
or, 3 X = 10
or, X = 10/3 = 3.34
Now, 5X - Y = 8
or,
Hence, for the given expression:
Answer:
The answer to your question is 20 feet
Step-by-step explanation:
Data
A = (-2, 1)
B = (4, 1)
C = (-2, -3)
D = (4, -3)
Process
1.- Calculate the distance from C and D
dCD =
dCD =
dCD = 6
2.- Calculate the distance from A to C
dAC =
dAC =
dAC = 4
3.- Calculate the perimeter
Perimeter = 2(dCD) + 2(dAC)
-Substitution
Perimeter = 2(6) + 2(4)
-Simplification
Perimeter = 12 + 8
-Result
Perimeter = 20 ft
