Skateboard for $50 that is 20% off, how much would you pay?" Your answer

$10

Step-by-step explanation:

two ways you can do this:

x 20 = 10.

OR

convert 20% into decimals (so 20/100 = 0.20) then multiply

0.20 x 50 = 10

they both work.

42

step-by-step explanation:

256/6=42

(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
