1/5x + 1/3 = -1/2x + 8/3

x= 10/3 or 3.3333333

Step-by-step explanation:

1/5x+1/3= -1/2+8/3

6x+10= -15x+80      Multiply both sides by 30

6x+15x=80-10        Move terms

21x=70             Combine like terms

/21   /21             Divide by 21

x= 10/3

x=3/10

Step-by-step explanation:

1/5x+1/3=-1/2x+ 8/3

1/5x+1/2x=8/3-1/3

2/10x+5/10x=7/3

7/10x=7/3

x=21/70

=3/10

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
