You said    C        = 2 π r

Divide each side by 2 : C / 2      =    π r

Divide each side by pi :    C / 2π =   r

Just divide 2pie on both sides so your equation would be C/2pie=r

3(x 2) 11 is greater than 20

Allushta [10]

3(x+2)+11>20
minus 11 both sides
3(x+2)>9
divide both sides by 3
x+2>3
minus 2 both sides
x>1

Solve the absolute value equation. If no solution write NO SOLUTION.<br> -{2x + 3] + 8<br> 12

Natasha2012 [34]

Answer:

If problem is "-|2x+3|+8=12"

then there is (<em>no solution.)</em>

Step-by-step explanation:

Let's solve your equation step-by-step.

−|2x+3|+8=12

Step 1: Add -8 to both sides.

−|2x+3|+8+−8=12+−8

−|2x+3|=4

Step 2: Divide both sides by -1.

−|2x+3|=4

-1 -1

|2x+3|=−4

Step 3: Solve Absolute Value.

|2x+3|=−4

No solutions Because absolute value is less than 0.

Solve for x - PLEASE NEED HELP, this is my 3rd time posting it.

mafiozo [28]

Answer:

$x=58$

Step-by-step explanation:

First, remember that the maximum degree of an angle totals 360°.

Since we already have 294°, this means that what is left must total $360\textdegree - 294\textdegree= 66\textdegree$ .

Therefore, this means that our two smaller angles must equal 66°. So:

$(36)+(x-28)=66$

Solve for x. Add on the left:

$x+8=66$

Subtract 8 from both sides. Therefore, the value of x is:

$x=58$
