Answer: <u>X=-3</u>

Step 1) Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

5*(x-4)+3*x-9*x-(6-(2*x+5)+8*x)=0

Step 2) ((5 • (x - 4) +  3x) -  9x) -  (6x + 1)  = 0

Step 3)  Pull out like factors :   -7x - 21  =   -7 • (x + 3)

Step 4)  -7 • (x + 3)  = 0

Step 5)  Solve :    -7   =  0  This equation has no solution.

A a non-zero constant never equals zero.

Step 6) Solve  :    x+3 = 0  

 Subtract  3  from both sides of the equation :  

x = -3

Find the circumference of the circle. Round your answer to the nearest hundredth. Use 3.14 or pi circle is 3 ft in radius
densk [106]

Answer:

18.84 feet

Step-by-step explanation:

The circumference of a circle can be found using:

c=π*d

The radius is given, but we have to find diameter. The diameter is twice the radius, or

d=2r

The radius is 3 feet. Substitute 3 in for r.

d=2*3

d=6

The diameter is 6 feet.

Now we have the diameter. We can substitute 6 in for d in the circumference formula. We can also substitute 3.14 in for pi.

c=π*d

c=3.14*6

c=18.84

The circumference is <u>18.84 feet</u>
