#4 me? ! ! what’s the solution set? 0.30(18)+0.05x=0.15(24+x)

The answer should be x= 18

Multiply the numbers

5.4+0.05x=0.15(24+x)

Move the variable to the left side c=and change the sign

5.4+0.05x-0.15x=3.0

collect terms

-0.1x=3.6+5.4

Divide both sides of the equation by -.01

x=18

(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
