Answer:
Equation: or
Solution:
Step-by-step explanation:
The formula that is used to calculate the perimeter of a square is:
Where "s" is the side lenght the square.
Knowing that Xin used 20 yards of fencing to build the walls of a square chicken coop (in which the lenght in yards of each wall is represented with "x"), you can identify that:
Then, you can susbtitute values into the formula :
Finally, you must solve for "x" in order to find its value.
This is:
Answer:
Easy Peasy!
Step-by-step explanation:
First we have to set up our equation:
(Let x= Temp. after 5 days)
Sorry, have to define variables. If I didn't do it in Middle School Tests, I get an automatic 0 for that question.
So, let's solve!
(If you didn't know what I did there, I just multiplied the rate of the decreasing and increasing temperature by the number of days it was in effect)
So, the temperature during the fifth day is 58.2 degrees.
Hope this helps!
P.S. Stay Safe!
