What is the value of x? enter your answer in the box. x =

Step-by-step explanation:

The angle bisector divides the segments so those on one side of it are proportional to those on the other side of it.

  (x+4)/8 = (2x+1)/12

  12(x +4) = 8(2x +1) . . . . . multiply by 96

  12x + 48 = 16x + 8 . . . . . eliminate parentheses

  40 = 4x . . . . . . . . . . . . . . add -12x-8

  10 = x . . . . . . . . . . . . . . . . divide by 4

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
