Answer:

Step-by-step explanation:

The area of a circle is pi*radius^2; the radius of this circle is 10 (20/2=10). Our area is then 100pi or ~314 square feet. A 2x2 square takes up 4 feet. 314/4 is equal to 78.5, or when rounded, 79

What is the solution of the inequality [3x+6]-2<10?

Ber [7]

Answer:

x > -3_2/3

Step-by-step explanation:

(3x+6)-2 < 10

Distribute

-6x-12 < 10

+12 +12

-6x < 22

-6x/-6 < 22/-6

When you divide by a negative number you flip the inequality

x > 22/-6

Simplify

x > -3_2/3

What is the solution: 256x + 2 = 43x + 9

ruslelena [56]

Answer:

$x = \bf \frac{7}{213}$

Step-by-step explanation:

To find the solution to the equation, we have to rearrange the equation to make $x$ the subject:

$256x + 2 = 43x + 9$

⇒ $256x + 2 - 2 = 43x + 9 - 2$ [Subtracting 2 from both sides]

⇒ $256x = 43x + 7$

⇒ $256x - 43x = 43x + 7 - 43x$ [Subtracting $43x$ from each side]

⇒ $213x = 7$

⇒ $\frac{213}{213}x = \frac{7}{213}$ [Diving both sides by 213]

⇒ $x = \bf \frac{7}{213}$
