Answer:
X =30
Step-by-step explanation:
= 60+90
=150
angle sum property
x+150=180
x=180- 150
x= 30
1 + 4x = -5 + 7x
<u> -4x </u> <u> - 4x </u>
1 = -5 + 3x
<u>+5 </u> <u>+5 </u>
6 = 3x

2 = x
Answer: x = 2
Hey there!
Let's first define our goal. Our goal here is to be able to isolate the variable, n, and solve for it by moving everything to the other side. We see that we have two sides of the equation, and by using the property of equality which states that whatever you do to one side you do to the other and the expression remains equal, we can solve this equation.
It looks like the only thing we have on the left side with n is that 6 1/2. In order to get rid of it, we must subtract it from both sides, because the property of equality states you must do the inverse operation.
We have:
n = 12 - 6 1/2
n = 5 1/2
Hope this helps!
The number of square tiles needed is 24 tiles
The formula for calculating the area of a rectangle is expressed as:
A = LW where:
L is the length
W is the width
For the rectangle:
Area = 12 feet × 8 feet
Area = 96ft²
For the square:
Area of a square = L²
Area of a square = 2²
Area of a square = 4ft²
Determine the number of square tiles that will cover the patio.
Number of square tiles needed = Area of rectangle/Area of square
Number of square tiles needed = 96/4
Number of square tiles needed = 24
Hence the number of square tiles needed is 24 tiles.
