Step-by-step explanation:
The area of the circle is determined through the equation,
A = πr²
Plug in the value of area
36 in² = πr² ; r = 3.385 in
The formula for the circumference of the circle is,
C = 2πr
Substitute the value of radius,
C = 2π(3.385 in) = 6.77π in
Thus, the circumference of the circle is 6.77π inches.
In this question, you're solving for x.
Solve for x:
2(4 - 8x) + 5(2x - 3) = 20 - 5x
Use the distributive property:
8 - 16x + 5(2x - 3) = 20 - 5x
8 - 16x + 10x - 15 = 20 - 5x
Combine like terms:
8 - 16x + 10x - 15 = 20 - 5x
8 - 6x - 15= 20 - 5x
-6x - 7 = 20 - 5x
Add 5x to both sides
-x - 7 = 20
Add 7 to both sides
-x = 27
Divide both sides by -1
x = -27
Answer:
x = -27
