24 cents.

11/66= 6
4/x= 6
4•6= 24
(proportions)

hope this is clear :))

8 x - 4 (5 - x) = -44

Sphinxa [80]

8 x - 4 (5 - x) = -44

mutiply the bracket by -4

(-4)(5) = -20

(-4)(-x)= 4x

8x-20+4x= -44

8x+4x-20= -44 ( combine like terms )

12x-20= -44

move -20 to the other side

sign changes from -20 to +20

12x-20+20= -44+20

12x= -44+20

12x= -24

divide both sides by 12

12x/12= -24/12

Answer: x= -2

The area of a circle is 9pi cm². Find its radius. <br>Please do this question with full solution:)

kirill115 [55]

Answer:

3 cm

Step-by-step explanation:

The formula for the area of a circle is:

$A = \pi r^2$

Where "r" represents the radius of the circle. We can substitute the given value for Area into the equation to solve for the radius.

<h3>Solve for Radius</h3>

$A=\pi r^2\\9\pi = \pi r^2$

Divide both sides by π

$9=r^2$

Take the square root of both sides

$\sqrt9=\sqrt {r^2}\\r=3$

The radius of the circle is 3 cm.
