Is the expression 5x-3(2x-4)is equiva
lent to the expression 12-x

Yes. They are equal.

Step-by-step explanation:

Let's simplify 5x-3(2x-4)

5x-3(2x-4)

5x-6x-12 (distribute)

-x+12

-x+12 and 12-x is the same thing just reversed.

so they are equal.

(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
