The horizontal axis represents variable A which means that variable A is ploted in the x-axis.
Each point is plotted (x, y) (i.e. the first number represents the value of variable A).
Therefore, the mean of variable A is
Answer:
5 feet
Step-by-step explanation:
We are given that
Width of rectangular pool=b=30 feet
Length of rectangular pool=l=40 feet
Area of rectangle=
Using the formula
Area of rectangular pool=
Total area enclosed within the perimeter of the deck=
Width of deck=x ft
Length of rectangular pool including wooden deck=40+2x ft
Width of rectangular pool including wooden deck=30+2x ft
Area of rectangular pool including wooden deck=
According to question
(Dividing by 4 on both sides)
It is not possible because width cannot be negative it is always natural number.
Hence, the width of the deck=5 ft
Answer: Second option, third option and fifth option.
Step-by-step explanation:
In order to solve this exercise it is important to remember the multiplication of signs:
Knowing that, you can distribute the sign and add the like terms. Repeat this procedure in each expression given in the exercise.
Therefore, you get:
You can identify that the expressions , and are equivalent after simplifying.
To solve for this, we need to get n by itself on one side, then solve from there.
Currently, our equation is 8n - 8 = 6n + 6.
Get n on one side, subtract 6n from both sides.
2n - 8 = 6
Add 8 to both sides.
2n = 14
Divide by 2 to get n.
n = 7.
I hope this helps!
