Answer:
<h2>a. The system of linear inequalities is

and

.</h2><h2>b. The solution is given in the figure.</h2><h2>c. The given scenario can happen.</h2>
Step-by-step explanation:
Let, I will buy x pounds Blueberries and y pounds Strawberries.
I need to collect at least 3 pounds of fruits.
Hence,
.
It also given that I can not spend more than $21, that is
.
If I will buy 4 pound Blueberries and 1 pound Strawberry, then x = 4 and y = 1.
Now, 4 + 1 = 5 > 3. First inequality is satisfied.
, Second inequality is also satisfied.
So the equation is n/4-4=14
then you +4 to both sides
n/4-4=14 so now the equation is n/4=18 then you multiply 18 by 4 and get 72
+4 +4
then to check your work
72/4-4=14
so N=72
Hope I helped :)

Answer:
P = 8.9k
Step-by-step explanation:
To find the perimeter, you need to add all three sides of the triangle.
P = (1.8k - 5) + (3.5 + 6.1k) + (k + 1.5)
Because you are adding all three expressions, you can remove the parentheses.
P = 1.8k - 5 + 3.5 + 6.1k + k + 1.5
Now you want to combine the variable (k).
P = (1.8k + 6.1k + k) - 5 + 3.5 + 1.5
P = (8.9k) - 5 + 3.5 + 1.5
Now you want to combine the constants.
P = (8.9k) - 0
You are left with:
P = 8.9k
